MOESM1 of The McMaster Toronto Arthritis patient preference questionnaire (MACTAR): a methodological study of reliability and minimal detectable change after a 6 week-period of acupuncture treatment in patients with rheumatoid arthritis

Additional file 1: Figure S1. Individual MACTAR data on all 8 participants. A celeration line is drawn through the two median values during the six A-phase assessments. The celeration line is then extended through the 10 B-phase assessments. A statistically significant change is defined as 9/10 assessments in the B-phase over or under the celeration line. BL = baseline interview, A1–A5 = assessments 1–5 during the A-phase, B1–B10 = assessments during the interventional B-Phase

Spearman correlation coefficients (r^s) for selected pairs of AIM-T₁ items within the lower limb and upper limb subscales in 635 patients (1207 assessments) and proportions of maximum AIM-T₁ scores at admission to inpatient departments (IPD) for lower (n = 321) and upper (n = 186) limb item scores and of minimum scores at discharge from outpatient departments (OPD) for lower (n = 91) and upper (n = 135) limb item scores.
