| CP vs C: p = 0.015* | |||||

| Duration of disease (Mean, Range) | 25.2 (8–60) | 18.1 (3–56) | 10.5 (5–16) | N/A | CP vs SP: p = 0.316 |

Unadjusted p-values are derived from pair-wise comparisons of psoriasis subtypes by the Mann-Whitney U test for continuous variables and Fisher’s exact test for categorical variables. The palmoplantar psoriasis group was not included in the statistical analyses due to small sample size. *p ≤ 0.05.
