Impact of Race on the Efficacy and Safety of Tofacitinib in Rheumatoid Arthritis: Post Hoc Analysis of Pooled Clinical Trials.

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.

Abstract
introductionRacial disparities in disease activity, clinical outcomes, and treatment survival persist despite advancements in rheumatoid arthritis (RA) therapies and clinical management. In this post hoc analysis of pooled data from the tofacitinib global clinical program, we evaluated the impact of race on the efficacy and safety of tofacitinib in patients with RA.
methodsData were pooled from 15 phase 2-3b/4 studies of patients with RA treated with tofacitinib 5 or 10 mg twice daily, adalimumab, or placebo. Outcomes were stratified by self-reported patient race (White/Black/Asian/Other). Efficacy outcomes to month 12 included: American College of Rheumatology (ACR)20/50/70 responses, Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] low disease activity (LDA) rates, least squares (LS) mean change from baseline (∆) in CDAI, DAS28-4 (ESR), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Pain [Visual Analog Scale (VAS)]. Odds ratios (ORs; 95% CI) versus placebo, and placebo-adjusted ∆LS means were calculated for active treatments using logistic regression model and mixed-effect model of repeated measurements, respectively. Safety outcomes were assessed throughout.
resultsA total of 6355 patients were included (White, 4145; Black, 213; Asian, 1348; Other, 649). For tofacitinib-treated patients, ORs for ACR20/50/70 responses and CDAI/DAS28-4(ESR) LDA rates through month 3 were generally numerically higher for White/Asian/Other versus Black patients. Across active treatments, trends toward higher placebo-adjusted improvements from baseline in CDAI, DAS28-4 (ESR), HAQ-DI, and Pain (VAS) were observed in Asian/Other versus White/Black patients. Numerically higher placebo responses in Black versus White/Asian/Other patients were generally observed across outcomes through month 12. Safety outcomes were mostly similar across treatment/racial groups.
conclusionsIn patients with RA, tofacitinib was efficacious across racial groups with similar safety outcomes; observed racial differences potentially reflect patient demographics or regional practice disparities.
