Statistica v 12.0 pl

Data were analysed using Statistica v.12.0.PL (StatSoft, Tulsa, OK, USA). Descriptive statistics (frequencies and percentages) are presented for demographic data and students’ opinions about functions and duties of a dermatologist (percent responses). Normality was verified using Shapiro-Wilk test. The differences between groups (males and females) were tested using the t-test. One-way ANOVA was applied to compare differences between non-medical students in different fields of study. Additionally, a post hoc least significant difference test was used to examine differences between different groups (fields of study). Finally, opinions about functions and duties of a dermatologist between males and females were compared with the Pearson χ² test. A p-value of less than 0.05 was considered as statistically significant for all of tests.

Statistica, v. 12.0 PL (StatSoft, Tulsa, USA) was used to perform statistical analysis. Pearson’s chi-squared test was applied to demonstrate the potential associations between defined categories. In the case of the ‘age’ category, the first interval (the youngest) was the arbitrary reference point for further comparisons. For the assessment of the multifactorial effect of the studied parameters on patient AUDIT-C responses, logistic regression models were used. Both the matching of the model and significance of the parameters were evaluated. P value <0.05 was considered as statistically significant.
