All types of lesions were to be identified and separately counted, i.e., non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (total lesion count at Baseline - total lesion count at Cycle 6)/(total lesion count at Baseline)\*100, so that improvement is indicated by a larger percent change.
