In 2016, three SLRs were conducted assessing variables, physical function, patient- reported outcomes and efficacy of biological disease- modifying antirheumatic drugs measures of structural damage.

All typical RA on two SLRs, one on safety and the present one on efficacy of study populations were included, methotrexate (MTX)- naïve pharmacological interventions in RA. or generally DMARD- naïve patients, csDMARD insufficient The body of evidence has grown vividly in the last 3 years, responders (IR), bDMARD-IR or tsDMARD-IR . Adequately especially regarding tsDMARDs inhibiting Janus Kinase inhib- defined control groups receiving either placebo or active treat- itor (JAKi), novel bDMARDs targeting new as well as established ment were mandatory for inclusion in this analysis. These pathways and trials comparing bDMARDs to other bDMARDs involved the efficacy of bDMARDs with or without csDMARD or tsDMARDs, providing important information on the compar- combination, head- to- head comparisons of bDMARDs and ative efficacy of these compounds.4 Further, studies on tapering switching between different bDMARDs, tapering and stopping and stopping treatment broaden the information base for rheu- bDMARDs, as well as the efficacy of tsDMARDs and the respec- matologists and patients on the question of possible disease tive head- to- head comparison to bDMARDs.

Risk of bias (RoB) in individual studies was assessed at study This SLR was conducted to update the evidence on efficacy of level using the Cochrane Collaborations Risk of Bias tool for pharmacological interventions in RA.

Descriptive forest plots were created using RevMan V.5.3 (Copenhagen: The Nordic Cochrane Centre, The Cochrane METHODS Collaboration, 2014). The EULAR updated standard operating procedures were followed,9 and an SLR protocol was developed and approved by the steering committee. RESULTS Studies eligible for inclusion in this SLR were randomised, The study selection process involved 15 037 references.
