Comparison of mean CSs between lesion types

LESION TYPE 1 n MEAN CS (SD) LESION TYPE 2 n MEAN CS (SD) t-TEST p-VALUE
Melanoma 127 3.5 (1.8) High-grade lesion 48 2.7 (1.3) 3.18 0.0019
Melanoma 127 3.5 (1.8) Low-grade dysplastic nevus 998 1.7 (1.5) 10.48 <0.0001
Melanoma 127 3.5 (1.8) Non-dysplastic nevus 217 1.6 (1.7) 9.10 <0.0001
Melanoma 127 3.5 (1.8) Benign lesion (non-nevus) 209 2.0 (2.2) 6.44 <0.0001
High-grade lesion 48 2.7 (1.3) Low-grade dysplastic nevus 998 1.7 (1.5) 5.07 <0.0001
High-grade lesion 48 2.7 (1.3) Non-dysplastic nevus 217 1.6 (1.7) 4.65 <0.0001

SD = standard deviation. p-value from Student’s t-test with unequal variance (Welch’s t-test). Using Bonferroni’s correction for multiple comparisons, p-values <0.05/15 = 0.0033 (bold) are statistically significant.
