Violin plots of endothelial cell grades for the criteria descemet folds, blur, and hexagonality before (0 h) and 24 h after CAP or control treatment at 2, 3, and 5 min treatment time (2 min. n = 17, 3 min. n = 6, 5 min. n = 7). The width of the violins reflects the count of the data points at a given grade, whereby the shape of the violins reflects the distribution of data points. The horizontal bars represent the median (red solid lines) and quartiles (red dashed lines). Statistical analysis: a non-parametric Friedman ANOVA with Bonferroni correction for 4 pairwise comparisons (CAP 0 h – CAP 24 h; Control 0 h – Control 24 h; CAP 0 h – Control 0 h; CAP 24 h – Control 24 h) was calculated for each criterium at each treatment time. *Level of significance: p < 0.0125.
