AN, total abscess and inflammatory nodule count; BMI, Body Mass Index; IHS4, Hidradenitis Suppurativa Severity Score System; OCP, oral contraceptive pills; VAS, Visual Analog Scale. Data are expressed as relative (absolute) frequencies and means (standard deviation (SD). The Student’s t test for independent samples was used to compare continuous variables and the chi-square test or Fisher’s exact test, as appropriate, were applied to compare categoric data. Two-tailed * p < 0.05 was considered statistically significant in all tests.
