Categorical data are presented as frequencies and percentages (N (%)); Continuous data departing from normality assumptions and ordinal data are presented as Median with its interquartile range (1st quartile–3rd quartile) (Me [IQR]). Chi2: Chi square test; MWU: Mann–Whitney U test; PCFS: Post-COVID-19 Functional Status. For binary data, the odds ratio with its 95% confidence interval were calculated [OR (95% CI)]. FFH: Fisher–Freeman–Halton exact test. T: independent samples T test.
