Repeated measurements were compared using a paired Student's t test or Wilcoxon signed rank test, as appropriate.
Continuous data were analyzed with Student's t test, Wilcoxon's signed rank test, as appropriate, and two-way analysis of variance (ANOVA) (on ranks when appropriate).
Comparisons of the outcomes at baseline and 3 months' follow-up were performed using the McNemar test for binominal variables and the Student t test or the Wilcoxon signed rank test, as appropriate, for continuous data.
Measurements from the day-to-day study were tested for normality using the Shapiro-Wilk test and compared using Student's paired t test or the signed Rank test as appropriate.
P refers to paired t test or Wilcoxon's Signed Rank Test, as appropriate, for continuous variables and the chi-square test for categorical variables PEEP indicates positive end-expiratory pressure, ZEEP indicates zero end-expiratory pressure, FRC indicates functional residual capacity.
P values were calculated by either the Student's t test or the non-parametric Wilcoxon signed rank test as appropriate.
