Additional file 3 of Sex differences in a cohort of COVID-19 Italian patients hospitalized during the first and second pandemic waves

Additional file 3: Supplementary Table 3. Complications occurring to COVID-19 patients during hospitalization. Row numbers (percentages) and statistical significances, indicated as P value (chi square test), are reported for females and males, first and second wave. aFor the variable "Mean number of complications", the numbers denote mean (standard deviation) and statistical significance is indicated as P value (t test). The normal distribution of this variable was tested using the Kolmogorov-Smirnov test. The three columns at the right-hand side report the results of logistic regressions using sex and wave as predictors and age as covariate of no interest. A not significant sex x wave interaction denotes that the percentages of males and females for each condition do not differ across waves. Statistically significant results are reported in bold. bLaboratory parameters not specifically associated with systemic inflammation and infections.
