  1. n = the number of samples. Data are presented as the median (25th percentile, 75th percentile). group A1: 0 < PHS ≤ 5%, group A2: 5 < PHS ≤ 10%, group B: 10 < PHS ≤ 20%, group C: PHS > 20%. Comparisons among group A1, group A2, group B, group C and the control group were determined by the nonparametric Mann–Whitney test. a indicates a significant difference compared with the control group. b indicates a significant difference compared with group A1. c indicates a significant difference compared with Group A2. d indicates a significant difference compared with Group B
