Statistical analysis
Descriptive statistics were given as mean ± standard deviation or median
[minimum-maximum] for continuous variables depending on their
distribution. Numbers and percentages were used for categorical
variables. The normal distribution of the numerical variables was
analyzed by the Kolmogorov-Smirnov test and checked by Q-Q plots and
histograms.
In comparing two independent groups, the Mann-Whitney U test was applied
for variables without normal distribution. Pearson chi-square and
Fisher’s exact tests were used in 2x2 tables to compare the differences
regarding categorical variables. Statistical analyses were performed
with Jamovi (version 1.6.3, retrieved from https://www.jamovi.org) and
JASP (version 0.13.1, retrieved from https://jasp-stats.org). The
significance level (p-value) was set at 0.05 in all statistical
analyses.
