Data are expressed as mean ± standard deviation. IS: Incentive Spirometer; RR: respiratory rate; pCO2: Mixed venous CO2 pressure; SpO2: Oxygen saturation; CI: Confidence interval; SMD: Standardized mean difference (based on Cohen’s d test), ANOVA: Analysis of variance, ANCOVA: Analysis of covariance.

*Analyzed using ANOVA/ANCOVA tests. a Crude analysis; b Adjusted to baseline measurement of the D-dimer, CRP, and CT-score (as covariances).
