2.3. Statistical Analysis

Clinical characteristics, laboratory and demographic data were evaluated and presented descriptively. The Shapiro–Wilk test was used to check for normality of continuous variables’ distribution. Fisher’s exact test and Mann–Whitney U test was used to compare the two groups. Survival analysis was evaluated using the Kaplan–Meier method, and the comparison between groups was made using the log-rank test. Risk factors associated with negative outcomes were investigated using a univariate, and subsequently a multivariable, Cox regression model by estimating the hazard ratio (HR) and its 95% confidence intervals (95% CI). Statistical analyses were performed using GraphPad Prism Software, version 10 (San Diego, CA, USA).
