Specific characteristics of the Faculty of Medicine Osijek
The specificity of the Faculty of Medicine Osijek lies in the combination of a regional clinical environment, growing scientific activity, international visibility and strong connection with the healthcare needs of eastern Croatia. In this context, statistical analysis often has to answer questions that are not only academic but also practically relevant for clinical practice, public health and healthcare planning.
Papers from Osijek may include small or medium-sized clinical samples, retrospective hospital databases, survey data, laboratory parameters, public health indicators, quality-of-life data, treatment outcomes and comparisons of patient groups. It is therefore necessary to select methods carefully, describe the sample correctly, control possible confounders and interpret results according to medical meaning.
Data types in medical papers
Projects related to the Faculty of Medicine Osijek may include demographic data, clinical outcomes, laboratory parameters, diagnostic tests, treatment outcomes, symptom scales, quality-of-life questionnaires, comorbidities, complications, hospitalization, mortality, survival, epidemiological indicators and public health data.
Clinical databases often include age, sex, diagnosis, disease stage, disease duration, treatment, laboratory values, imaging findings, surgical data, complications and treatment outcomes. Questionnaire studies may include instrument validation, scale reliability, factor structure, correlations between psychological and clinical variables, and differences between patient groups. For psychological and questionnaire topics, the F3 hub may be relevant: statistical help for humanities and social sciences, and for validation of instruments and rehabilitation assessments the F6 hub: questionnaires, assessments and instrument validation.
Medical research design
Retrospective clinical studies
Retrospective studies use existing hospital databases, medical records, laboratory registries or archived diagnostic findings. The advantage is data availability; challenges include missing values, heterogeneous documentation, different measurement methods and limited control over original data collection.
Prospective studies
Prospective studies allow better control over measurements, follow-up and outcome definition. Primary and secondary outcomes, inclusion and exclusion criteria, sample size and statistical analysis plan should be defined in advance.
Cross-sectional and epidemiological studies
Cross-sectional studies assess prevalence, risk factors, attitudes, quality of life, knowledge, behavior or relationships between clinical and sociodemographic indicators at a single time point. Epidemiological studies may include incidence, prevalence, odds ratios, relative risks and risk factor analysis.
Longitudinal studies and repeated measurements
Longitudinal studies follow patients over time, for example before and after therapy, during rehabilitation or across several follow-up visits. Such data require methods that account for dependence between repeated measurements. For rehabilitation and functional outcomes, the F4 hub may be useful: sports and kinesiology research.
Clinical and intervention studies
Clinical and intervention studies require careful planning, clear inclusion and exclusion criteria, defined outcomes, control of possible confounders, transparent reporting and explanation of clinical relevance.
Important statistical methods
Descriptive statistics
Descriptive statistics describe sample structure: age, sex, diagnoses, clinical characteristics, laboratory values and outcomes. Depending on distribution, mean and standard deviation or median and interquartile range are reported.
Group comparison tests
Group comparisons use t-test, Mann-Whitney U test, ANOVA, Kruskal-Wallis test, chi-square test and Fisher’s exact test. Method selection depends on variable type, distribution, group size and research question.
Correlation analysis
Correlation analysis examines relationships between laboratory values, clinical scales, disease duration, symptom intensity, functional status, quality of life and other continuous or ordinal indicators.
Regression analysis
Linear, logistic and ordinal regression are used to evaluate predictors of outcomes. Logistic regression is especially important when the outcome is binary, such as complication, positive finding, treatment response, hospitalization or mortality.
ROC analysis
ROC analysis evaluates diagnostic accuracy of biomarkers, laboratory parameters and clinical tests. It presents sensitivity, specificity, AUC and possible cut-off values.
Survival analysis
Kaplan-Meier curves and Cox regression are used when time-to-event outcomes are important, such as time to relapse, death, complication, hospitalization or treatment failure.
Reliability analysis and instrument validation
For questionnaires and scales, Cronbach’s alpha, item analysis, factor analysis, correlations and construct validity are used. These methods are important in clinical, psychological, rehabilitation and public health research.
Multivariate methods
Multivariate methods are used when many related variables are present. In medical papers they can help identify patient profiles, risk classes, biomarker patterns or dimensions of complex data.
SPSS analysis and interpretation
SPSS is frequently used in medical papers because it supports group comparisons, correlations, regression, ROC analysis, reliability analysis and graphical presentation. Technical execution alone is not enough.
In medicine, results must be interpreted statistically and clinically. A p-value shows statistical significance, but not automatically effect size, clinical importance or applicability. Confidence intervals, effect sizes, odds ratios, relative risks, AUC values and other indicators are therefore important.
Sample size and statistical power
Medical studies often require sample size planning. Too small a sample may fail to confirm a real effect, while very large samples may show statistically significant but clinically small differences. Sample size should be connected with the primary outcome, expected effect size, significance level and desired power.
Typical topics for Osijek
Typical topics include clinical studies, retrospective patient analyses, prospective studies, medicine in German, regional public health topics, epidemiology of Slavonia and Baranja, laboratory biomarkers, diagnostic accuracy, treatment outcomes, quality of life, questionnaire validation, medical rehabilitation, neurological and psychiatric scales, oncology outcomes, cardiovascular risk factors, pediatric data and survival analysis.
