Pharmacy in Mostar is treated here within the context of pharmacy and pharmaceutical studies in Mostar, with a focus on students working on bachelor’s, master’s, doctoral and scientific papers in pharmacy, pharmaceutical analytics, pharmaceutical chemistry, biochemistry, clinical pharmacy, pharmacoepidemiology, laboratory diagnostics and public health. Pharmacy is a strongly interdisciplinary field because it connects medicine, chemistry, biology, laboratory work, therapy, drug safety and the healthcare system.
In such papers, statistical data analysis has a particularly important role. Data may originate from laboratory measurements, validation of analytical methods, stability testing of pharmaceutical formulations, analysis of biochemical parameters, pharmacoepidemiological databases, clinical pharmacy research or questionnaires on adherence, knowledge, attitudes, self-medication, adverse effects and rational drug use. For this reason, statistical analysis must be connected with the research question and the pharmaceutical meaning of the results, rather than being formally performed in SPSS without methodological justification.
Statistical data analysis for pharmacy in Mostar
Pharmaceutical research in Mostar may include laboratory, experimental, clinical pharmacy, pharmacoepidemiological and survey-based studies. Laboratory papers often analyze active substance concentrations, biochemical values, pH values, absorbance, formulation stability, disintegration time, release rate, quality control results or validation parameters of analytical methods. In clinical pharmacy research, the focus may be on therapy adherence, adverse effects, drug interactions, prescribing patterns, rational drug use, patient knowledge, quality of pharmaceutical care and the role of pharmacists in the healthcare system.
Pharmaceutical data require a careful statistical approach because not all data have the same nature. Analyzing a laboratory concentration is not the same as analyzing formulation stability over time, a method validation result, frequency of adverse effects, an adherence scale or a Likert attitude scale. Each variable has its own measurement level, pharmaceutical context and interpretation that must be understandable in the methodology and results sections.
SPSS is frequently used because it allows descriptive statistics, group comparisons, correlations, regression models, reliability analysis and graphical presentation of results. However, SPSS cannot decide which method is appropriate. Before analysis, the dataset must be prepared, variables defined, the sample described, data distribution checked, the unit of analysis determined and the statistical test connected with the hypotheses. A useful starting point is the page on statistical help for SPSS, theses, dissertations and research, while research from Bosnia and Herzegovina is naturally connected with statistical support for Bosnia and Herzegovina.
Nature of pharmaceutical data
Pharmaceutical research often includes continuous, categorical and ordinal variables. Continuous variables may include substance concentration, absorbance, pH value, biochemical parameter, stability, release time, quality control value, number of therapy days or laboratory indicator. Categorical variables may include sex, treatment group, drug type, pharmaceutical form, presence of adverse effects, adherence status, type of intervention or outcome. Ordinal variables often occur in Likert scales, satisfaction levels, knowledge assessment, patient attitudes and perception of pharmaceutical care.
In laboratory and analytical papers, it is important to distinguish between sample, repetition, batch and measurement. If the same sample is measured multiple times, those repetitions are not the same as fully independent samples. In method validation, precision, accuracy, linearity, repeatability, limit of detection and limit of quantification must be clearly presented depending on the aim of the paper. In formulation stability research, the statistical result should be connected with the real pharmaceutical meaning of change over time.
In survey-based and clinical pharmacy research, data are often related to patients, students, pharmacists or other healthcare professionals. Such papers may include scales of knowledge, attitudes, adherence, satisfaction or perception of pharmaceutical care. It is important to clearly describe the number of items, response range, scoring direction, possible subscales and meaning of higher values. If a total score is used, reliability of the scale often needs to be assessed, for example with Cronbach’s alpha.
Research design in pharmacy
Experimental laboratory studies may include formulation comparisons, validation of analytical methods, stability testing, release studies, influence of storage conditions or quality analysis of pharmaceutical products. Such papers should clearly present the number of samples, number of repetitions, measurement conditions, method used and interpretation criteria.
Cross-sectional studies are common when examining knowledge, attitudes, self-medication, use of dietary supplements, therapy adherence, patient satisfaction or perception of pharmaceutical care. They describe the situation at one point in time, but they do not allow direct causal conclusions.
Retrospective studies may use existing records, laboratory findings, medical documentation, medication prescribing data, drug consumption data or reported adverse effects. Their advantage is data availability, while limitations include documentation quality, missing values and lack of control over the original data collection.
Prospective studies allow more precise planning of measurement and follow-up. They may be used to evaluate pharmaceutical interventions, educational programmes, adherence monitoring, changes in therapeutic parameters or comparisons of outcomes before and after an intervention. In repeated-measures studies, the dependence of observations within the same participant must be considered.
Common statistical methods
Descriptive statistics describe the sample, laboratory values, survey results and basic characteristics of variables. For continuous variables, mean and standard deviation or median and interquartile range are reported depending on distribution. For categorical variables, frequencies and percentages are shown. In laboratory papers, descriptive presentation is especially important because it shows measurement variability and stability of obtained values.
Tests of differences are used when comparing two or more groups. The t-test and ANOVA may be appropriate for approximately normally distributed continuous data, while the Mann-Whitney U test and Kruskal-Wallis test are often more suitable for ordinal or non-normally distributed data. The chi-square test and Fisher’s exact test are used for categorical variables such as adverse effects, adherence or differences between patient groups.
Correlation analysis examines relationships between variables. In pharmacy, this may include the relationship between concentration and time, stability and storage conditions, knowledge and adherence, satisfaction and perception of pharmaceutical care or laboratory parameters and clinical outcomes. Pearson correlation is suitable for approximately normally distributed continuous variables, while Spearman correlation is suitable for ordinal data and non-normal distributions.
Regression analysis is used to estimate which factors predict a certain outcome. Linear regression is used for continuous outcomes, logistic regression for binary outcomes and ordinal regression for ordinal outcomes. In pharmaceutical research, regression may show factors associated with adherence, adverse effects, patient satisfaction, rational drug use, laboratory parameters or therapeutic outcomes.
ROC analysis may be useful when assessing the diagnostic value of a biomarker, laboratory test or cut-off value. In method validation, linearity, precision, accuracy, repeatability, limit of detection and limit of quantification may be important. The statistical presentation must correspond to the aim of validation and to the way the result will be used in pharmaceutical or laboratory practice.
SPSS analysis and interpretation
SPSS output should not simply be copied into the paper. Results should be transformed into clear tables and text that correspond to the research question. In pharmaceutical papers, it is particularly important to explain what a statistical result means for formulation stability, drug quality, analytical method, patient adherence, adverse effects or pharmaceutical care. The p-value should be interpreted together with effect size, direction of difference, confidence intervals and practical meaning of the finding.
For practical work, the complete SPSS guide is useful, and when choosing a method the article which statistical method to use and when may help. If the paper is still in the planning stage, the practical guide for students and researchers is also useful because many analytical problems can be avoided through careful planning of the dataset and variables.
Sample size and planning
Sample size in pharmaceutical research depends on the study design. In laboratory papers, the number of samples, repetitions, batches and measurements should be distinguished. In survey studies, the number of participants and distribution across groups are important. In clinical pharmacy studies, sample size should be connected with the primary outcome, expected effect size and planned statistical method.
When students are unsure how many participants or measurements are needed, the article how many participants are needed can be useful. In retrospective papers, the available number of cases, missing values and limitations of available data should be clearly described.
Ethics of statistical support and author responsibility
Statistical support may include dataset preparation, method selection, SPSS analysis, table preparation and suggested interpretation. The author remains responsible for the final text, conclusions and academic interpretation. This distinction is important and is further explained in the article is it allowed to get statistical help.
Workflow
Collaboration usually begins with reviewing the topic, aims, hypotheses and available dataset. Then the variable structure is checked, statistical methods are proposed, analysis is performed and result tables are prepared. A practical description of this process is available in the article how working with a statistician looks step by step.
I prepare statistical results and suggest how they can be presented in the paper. The author remains responsible for the final text and interpretation of the results.
