males (84.7% versus 63.5%) and the mean baseline noninflammatory lesion count was a little higher than that noted in the adult males (45.5 versus 39.8), although the proportion of subjects classified as severe (EGSS=4) was slightly lower in the adolescent male population (11.5% versus 12.9%).

Efficacy Evaluation
Evaluator’s Global Severity Score (EGSS) Significantly more adult male subjects achieved at least a 2-grade improvement in EGSS with tazarotene 0.045% lotion compared with adolescent male subjects at week 12 (42.1% versus 24.6%, P=0.006); see Figure 1. Differences were significant from week 8. In addition, 33.0% of adult males were considered ‘treatment successes’ (defined as at least a 2-grade improvement in EGSS and ‘clear’ or ‘almost clear’) compared with 21.6% of adolescent subjects treated with tazarotene 0.045% lotion (P=0.059).
