Box plots presenting comparisons of abnormal breathing duration for each of four features of the abnormal breathing in control group. Median values are indicated by a horizontal bar within each box; bars above and below each box represent 25 and 75 percentiles, end of vertical lines denote 5 and 95 percentiles, and black circles are outliers. Comparisons within the feature were performed by Wilcoxon signed rank test. P < 0.0125 was considered statistically significant for adjusting the multiplicity of the comparison.
