Analysis of the Impact of Tofacitinib Treatment on Weight and Body Mass Index in Patients With Rheumatoid Arthritis.
Article in ACR open rheumatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThis post hoc analysis evaluated change from baseline (Δ) in weight/body mass index (BMI) and association with disease activity or lipid changes in tofacitinib-treated patients with rheumatoid arthritis (RA).
methodsData up to month 12 were pooled from eight phase 3 and 3b/4 studies of patients with RA receiving tofacitinib 5 or 10 mg twice daily or tofacitinib 11 mg modified-release once daily (alone or combined with conventional synthetic disease-modifying antirheumatic drugs), or placebo. Assessments included Δweight/BMI and the proportion of patients with weight gain ≥5%, at months 3, 6, and 12. Correlations between ∆weight/∆BMI and baseline/∆Disease Activity Score in 28 joints, erythrocyte sedimentation rate (DAS28-4[ESR]), baseline C-reactive protein (CRP), and ∆lipids were assessed. Statistical analysis included a longitudinal linear mixed model for repeated measures.
resultsThe analysis included 5,335 patients (tofacitinib 5 mg twice daily [n = 2,349], 10 mg twice daily [n = 1,611], 11 mg once daily [n = 694], and placebo [n = 681]). Increases in least squares mean Δweight and ΔBMI were significantly greater (P < 0.05) at months 3 and 6 with all tofacitinib doses versus placebo; increases continued to month 12. Significantly greater (at least P < 0.05) proportions of tofacitinib-treated patients (all doses) had weight gain ≥5% at months 3 and 6 versus placebo. There were weak correlations between weight/BMI changes with tofacitinib and DAS28-4(ESR), baseline CRP, or lipid changes.
conclusionPatients receiving tofacitinib experienced weight and BMI changes (primarily increases) over time, with weak correlations with disease activity or lipids.
