Assessing disease activity using the pediatric Crohn’s disease activity index: Can we use subjective or objective parameters alone?

Table 3 Correct and incorrect identification of remitters and non-remitters

Remitters at Q1 (n = 397)	292 (73.8)	105 (26.2)	284 (71.5)	113 (28.5)
Non-remitters at Q1 (n = 273)	46 (16.7)	227 (83.3)	58 (21.2)	215 (78.8)
Remitters at Q4 (n = 274)	202 (73.7)	72 (26.3)	204 (74.5)	70 (25.3)
Non-remitters at Q4 (n = 200)	45 (22.5)	155 (77.5)	56 (28.0)	144 (72.0)

Subjective subscale is composed of abdominal pain and stooling; Objective subscale is composed of erythrocyte sedimentation rate, albumin, weight, height velocity, and perirectal examination. Shaded cells = number of patients that would be incorrectly (or differently) classified as having active or inactive disease based on the subjective components alone (e.g., At the Q1 time point, 397 patients were classified as being in remission, but based on the subjective only scoring, 292 (73.8%) of those patients would be classified as being in remission, while the other 26% would be classified as having active disease).
