We describe two simple, reproducible scoring systems for assessing acne severity, and we emphasize the technical problems which could invalidate either technique. Constant baseline data is desirable for any clinical trial, and our data clearly show that acne patients should ideally be off all treatment for at least 2 months before the start of a therapeutic trial.
我们描述了两种用于评估痤疮严重程度的简单、可重复的评分系统，并强调了可能使任何一种技术无效的技术问题。任何临床试验都需要恒定的基线数据，我们的数据清楚地表明，痤疮患者在治疗试验开始前理想情况下应停止所有治疗至少2个月。
