Predictors of change in bodily pain in early rheumatoid arthritis: an inception cohort study.

ABSTRACT:

Objective

To investigate possible predictors for lack of pain improvement after 1 year of treatment for early rheumatoid arthritis (RA).

Methods

The Early Rheumatoid Arthritis Network (ERAN) database was used for analysis of baseline and 1-year pain data. The ERAN is a hospital-based inception cohort of 1,189 people. Short Form 36 questionnaire bodily pain scores were used to calculate change in pain at 1 year as the outcome. The proportion of the Disease Activity Score in 28 joints (DAS28) attributable to patient-reported components (joint tenderness and visual analog scale score; DAS28-P) at baseline was derived as a predictor. Predictors of less improvement in pain were investigated using adjusted odds ratios (OR(adj) ) generated by logistic regression, adjusting for 14 a
