p21 prevalence differed significantly between most nevus and melanoma categories, and the overall trend with progression was highly significant ( r = 0.528, P = 3 × 10 −6 ; Table 1 ).
p21 prevalence differed significantly between most nevus and melanoma categories, and the overall trend with progression was highly significant ( r = 0.528, P = 3 × 10 −6 ; Table 1 ).
There was a strong trend of rising expression with progression (Figure 1 B; r = 0.647; P < 0.0001).
