All data were analyzed with SPSS Version 17.0(SPSS Inc., Chicago, IL). For hypothesis testing, the alpha level was set at 0.05 (two-tailed). For demographic and clinical characteristics of patients, nominal and ordinal data were expressed as percentages.
Continuous variables were expressed as means and standard deviations and analyzed. Differences between groups were assessed using the Chisquare test or Fisher’s exact test for nominal data and the Manny Whitney U test for ordinal data. Kendall’s coefficient of concordance was used as the reliability statistic for OAG measurement among raters. Friedman’s test was used to analyze repeated measures of the OAG
scores obtained at enrollment, before extubation, and 48 hours after extubation. The Wilcoxon signedrank test was used for post hoc analyses followed by a
Bonferroni correction with a revised alpha level of
0.017. Difference and effect size of changes between
enrollment and before extubation, before extubation
and 48 hours after extubation, and enrollment
