Comparing persistence of new biologics to conventional anti-TNF alphas in adult patients with inflammatory bowel disease: a systematic review and meta-analysis protocol.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundBiological therapy is a cornerstone of managing moderate-to-severe inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD). New biologics have been evolving over the past 20 years and selection of an agent remains challenging.Drug persistence measures the duration of time from initiation to discontinuation of a therapy, which can be a surrogate marker of drug tolerance and efficacy.
objectivesThe study aimed to compare drug persistence of new generation biologics for the treatment of UC and CD (vedolizumab, ustekinumab, certolizumab, tofacitinib, natalizumab and golimumab) with conventional anti-tumor necroisis factor alphas (anti-TNF alphas) (adalimumab and infliximab) in adult patients with IBD. Results of the study may provide guidance on the preferred first and subsequent lines of biological treatments in patients with IBD. METHODS AND ANALYSIS: Search via electronic databases including EMBASE, MEDLINE, PubMed and clinical trial databases will be conducted on 10 March 2023 with eligible studies included from inception of 2017 to 2023. The primary outcomes are 1-year persistence of individual biologics with comparison of new biologics versus conventional anti-TNF alphas. A meta-analysis will be conducted using Review Manager V.5 and outcome will be presented as relative risk. Heterogeneity will be assessed with forest plot, χ ETHICS AND DISSEMINATION: Ethical approval is not required as no private information of participants will be used. Results of the present study will be disseminated in a peer-reviewed journal or conference presentation. PROSPERO REGISTRATION NUMBER: CRD42023392236.
