A comparative study of PF-06438179/GP1111 (an infliximab biosimilar) and reference infliximab in patients with moderate to severe active rheumatoid arthritis: A subgroup analysis.
Trial report in International journal of rheumatic diseases, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
aimPF-06438179/GP1111 (PF-SZ-IFX) is a biosimilar of reference infliximab (Remicade
methodsPatients with rheumatoid arthritis were randomized 1:1 to PF-SZ-IFX (n = 324) or IFX-EU (n = 326); study drug (3 mg/kg) was administered intravenously at weeks 0, 2, and 6, then every 8 weeks thereafter. Subgroup analyses of efficacy endpoints such as American College of Rheumatology criteria for ≥20% clinical improvement (ACR20), change in high-sensitivity C-reactive protein (hs-CRP), and change in Disease Activity Score in 28 joints, four components based on hs-CRP (DAS28-CRP) at weeks 14 and 30 were performed by age, gender, race, region, immunogenicity status, and treatment history.
resultsOverall, ACR20 response rates as well as changes in DAS28-CRP and hs-CRP at week 14 were similar between PF-SZ-IFX and IFX-EU within the subgroups of age, gender, race, region, treatment history, and immunogenicity status. Results to week 30 support overall similarity in efficacy between the two treatment arms in all subgroups.
conclusionOverall, PF-SZ-IFX and IFX-EU were similar in efficacy within the analyzed subgroups of age, gender, race, region, treatment history, and immunogenicity status. The efficacy results from these subgroup analyses were aligned with the previously described results for the overall population up to week 30.
