The disease activity in ulcerative colitis and Crohn's disease was studied. Parameters found to reflect the disease activity were given scores from 1 to 4. The score obtained by a patient compared with the maximum scores gives the percentage disease activity. The regressions between the percentage disease activity and the ESR in ulcerative colitis and Crohn's disease were r=0.68 (p less than 0.001) and r=0.48 (p less than 0.001), respectively. The different activity parameters have different time response curves explaining the occasional slight correlation. The percentage disease activity represents the mean activity of the different parameters at a given time. It is proposed to define slight, moderate, and severe ulcerative colitis or Crohn's disease as percentage disease activity of less than 30, 30-70 and greater than 70 per cent, respectively.
对溃疡性结肠炎和克罗恩病的疾病活动情况进行了研究。发现反映疾病活动的参数被赋予1至4分。患者获得的分数与最高分相比得出疾病活动百分比。溃疡性结肠炎和克罗恩病中疾病活动百分比与红细胞沉降率（ESR）之间的回归系数分别为r = 0.68（p < 0.001）和r = 0.48（p < 0.001）。不同的活动参数具有不同的时间反应曲线，这解释了偶尔出现的轻微相关性。疾病活动百分比代表给定时间不同参数的平均活动情况。建议将轻度、中度和重度溃疡性结肠炎或克罗恩病分别定义为疾病活动百分比低于30%、30%-70%和高于70%。
