Efficacy, safety, and immunogenicity of biosimilars compared with the biologic etanercept in patients with rheumatoid arthritis: a systematic review and meta-analysis.
Synthesis in Systematic reviews, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBiosimilar etanercept presents itself as an innovative therapeutic opportunity for inflammatory and autoimmune diseases, however, its efficacy, safety, and immunogenicity in relation to the reference biological agent for the treatment of rheumatoid arthritis is still questioned. With this in mind, this study aimed to verify the efficacy, safety, and immunogenicity of the use of the biosimilar etanercept in relation to the reference biologic in patients over 18 years of age with rheumatoid arthritis.
methodsA systematic review with meta-analysis was performed in accordance with the parameters of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) selecting only Phase III randomized clinical trials. The search strategy was constructed with the MeSH terms "Etanercept", "Biological Products", "Arthritis, Rheumatoid", "Biosimilar Pharmaceuticals" and was performed in Medline via PubMed, Embase, the Cochrane Library, Web of Science, EBSCO and Lilacs in January 2023. The analysis measures were relative risk (RR) for dichotomous data and mean difference (MD) for continuous data. The statistical analysis for preparing meta-analyses was developed by the Review Manager 5.1.4 software.
resultsThis systematic review selected 6 eligible studies with a sample population of n = 2355. The main efficacy outcomes showed that both drugs did not present statistically significant differences in ACR20, ACR50, and ACR70 responses within 6 months (RR 1.00; 95% CI = 0.94 to 1.07; RR 1.09; 95% CI = 0.94 to 1.26; RR 1.04; 95% CI = 0.82 to 1.31, respectively), with I
conclusionsThus, this review found that biosimilar etanercept had efficacy, safety, and immunogenicity similar to those for the biological reference. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered on the PROSPERO platform under number CRD42020166610.
