SD: standard deviation. aScores were compared between fingernails at 0 mm and 2 mm in males using Wilcoxon signed-rank test. bScores were compared between fingernails at 0 mm and 2 mm in females using Wilcoxon signed-rank test. cScores were compared between males and females with fingernails at 2 mm using Mann-Whitney test. *p<0.05, **p<0.01
