Causes of the Failure of Biological Therapy at a Tertiary Center: A Cross-Sectional Retrospective Study.
Article in Cureus, 2021. 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
Introduction Rheumatoid arthritis (RA) is one of the most commonly encountered autoimmune diseases. Treatment generally includes disease-modifying anti-rheumatic drugs (DMARDs) and/or biological therapy. However, a significant proportion of the patients do not respond to treatment either as a (primary failure) or lose efficacy over time (secondary failure). Several factors are assumed to influence these conditions. Objectives To estimate the prevalence of failure of biological therapy in patients with RA and its causes. Methods A total of 335 RA patients who were diagnosed at a tertiary center in Jeddah, Saudi Arabia, and had a failure after receiving biological therapy were included in this study. Several variables were considered; patient's socio-demographic data, comorbid conditions, types of biological therapy, the duration of using biological therapy in months, number of biological therapies, allergic reactions, disease activity, and treatment duration. Results Overall the prevalence of failure to biological therapy was 58%; 77% primary failure and 23% secondary failure. Patients with negative rheumatoid factor (RF) (p=0.006), using low-dose steroids, and with a longer disease duration had a significant failure of biological therapy (p=0.023). Conclusion A high percentage of RA patients had a failure of biological therapy. A multicentric trial is recommended to look for additional factors.
