Additional file 1 of Association between a remimazolam–propofol combination for maintenance of anesthesia and extubation time: a propensity score analysis

Supplementary Material 1: Supplementary Fig. 1. Box-and-whisker plots showing the distribution of time intervals from discontinuation of remimazolam and propofol to extubation in the RB + PROP group (n = 75). Each pair of corresponding cases is connected by a line to illustrate the within-patient differences. The Wilcoxon signed-rank test was applied to compare the paired data.
