Biosimilar infliximab versus originator in Crohn's disease anti-TNF-α naïve and non-naïve patients.
Article in Przeglad gastroenterologiczny, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
introductionData comparing response to originator and biosimilar infliximab in anti-TNF-α naïve and non-naïve Crohn's disease patients is limited.
aimTo assess the efficacy, safety, and tolerability of a biosimilar infliximab in comparison to the originator drug in anti-TNF-α naïve and non-naïve Crohn's disease patients. Data comparing response in those two groups of patients are limited. MATERIAL AND
methodsThis retrospective single-centre study enrolled 168 adult Crohn's disease patients treated for 1 year with infliximab originator or biosimilar. Assessment included achievement of clinical remission (during induction and maintenance therapy and follow-up period - 24 months) and occurrence of adverse events.
resultsForty-seven patients taking infliximab and 68 on biosimilar were anti-TNF-α naïve. There were no differences in clinical remission rate between naïve and non-naïve patients after 1 year of treatment (infliximab - 80.9% and 73.1%, respectively; biosimilar - 79.4% and 74.1%, respectively). The relapse rate during the follow-up period was higher in anti-TNF-α non-naïve patients (
conclusionsThis is a study comparing anti-TNF-α naïve and non-naïve patients with Crohn's disease. Relapse rate during follow-up was significantly higher in anti-TNF-α non-naïve patients, but with no significant differences between originator and biosimilar.
