Variable | Patients without a period of remission (n = 283) | Patients with ⩾1 period of remission (n = 142) | p Value† |
---|---|---|---|

†Significant different between the group of patients with remission and group of patients without remission using unpaired two sided t test for normally distributed data (*) and Mann–Whitney U test for non-normally distributed data. | |||

Ranges for variables are as follows: ESR, 1 to 140; morning stiffness, 0 to 720; pain, 0 to 100 = worst score; joint score, 0 to 534; general wellbeing, 0 to 100 = worst score; grip strength, 0–120 = best score; functional disability, 0 to 3 = worst score; radiographic damage, 0 to 448. | |||

ESR, erythrocyte sedimentation rate; HAQ, health assessment questionnaire; VAS, visual analogue scale. | |||
