In both groups, functional ability improved and radiological progression of joints was minimal. At least one adverse event was reported in 96% of the patients in both groups. In total, 25 serious adverse events occurred: 9 vs 16 in COBRA and COBRA-light, respectively. Treatment actually instituted was often less intensive than required by the protocol: of the total population, 108 patients (67%) required etanercept (more in the COBRA-light group), but only 67 of these (62%) actually received it.Conclusions Intensive COBRA or COBRA-light therapy has major, comparably favourable effects on disease activity, functional ability and radiological outcome after 1 year in patients with early RA. Protocolised addition of etanercept was often not implemented by treating rheumatologists, and patients receiving it appeared to have limited added benefit, probably because of low disease activity levels at its initiation.Trial registration number: ISRCTN55552928.
