Numerous network meta-analyses have provided comparative efficacy and safety data for treatments in psoriaasis over a short period (8-24 weeks). So, we conducted a systematic review to map the design and synthesize all 1-year efficacy and safety data of biologic treatments for moderate-to-severe psoriasis from the randomized controlled trials (RCTs) included in the Cochrane review (Sbidian et al., 2022). Among the 81 RCTs included, many different designs are presented after the induction phase. Within a single trial, each arm (placebo, intervention, active comparator) could have a different design: single randomization; crossover; re-randomization. In addition, there was selection of patients into each arm based on the level of PASI response achieved or PGA achieved.
