Analysis of patient characteristics revealed that older and less healthy patients with RA were more likely to receive non-TNFi bDMARDs as a first bDMARD compared to other treatments.This study aimed to describe patient characteristics at initiation of bDMARD treatment at two-time points: first bDMARD initiation and switch to second bDMARD after TNFi treatment. The second aim of the study was to estimate the potential of treatment channelling to confound results in comparative treatment studies i...
