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
Background: Methotrexate is central to the management of rheumatoid arthritis (RA). However, its use is often limited by methotrexate intolerance. Objectives: This study aims to explore the association between alternative methotrexate dosing methods and methotrexate intolerance. Design: A cross-sectional study. Methods: A cross-sectional survey was conducted on patients with RA receiving methotrexate for at least 3 months at the outpatient clinic of King Saud University Medical City, Riyadh, Saudi Arabia. The electronic survey collected data on demographics, marital and educational status, methotrexate use, Methotrexate Intolerance Severity Score (MISS), and Health Assessment Questionnaire. Statistical analyses (univariate and linear or logistic regression) were conducted to evaluate the associations between the administration methods and methotrexate intolerance (MISS ⩾6). Results: The study included 154 patients, predominantly female (89%; mean age (standard deviation, ±SD): 50 (±12) years). Methotrexate tolerance was observed in 64% of the participants, while 36% had a MISS above the cutoff point of 6, indicating intolerance. Methotrexate-intolerant patients were younger (mean age (±SD): 47 (±12) years) than tolerant patients (mean age (±SD): 54 (±12) years; Conclusion: Methotrexate tolerance was not associated with different administration methods: split-dose versus single weekly dose, or subcutaneous versus oral administration.
