Early Improvements with Guselkumab Associate with Sustained Control of Psoriatic Arthritis: Post hoc Analyses of Two Phase 3 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
introductionPatterns of treatment response can inform clinical decision-making. This study assessed the course and impact of achieving minimal clinically important improvement (MCII) in clinical measures and patient-reported outcomes (PROs) with guselkumab in patients with active psoriatic arthritis (PsA).
methodsPost hoc analyses evaluated 1120 patients with PsA receiving guselkumab every 4 or 8 weeks (Q4W/Q8W) or placebo from DISCOVER-1 (31% tumor necrosis factor inhibitor-experienced) and DISCOVER-2 (biologic-naïve). Achievement of MCII in clinical Disease Activity Index for PsA (cDAPSA), patient global assessment (PtGA) of arthritis, PtGA of psoriasis, patient-reported pain, Functional Assessment of Chronic Illness Therapy-Fatigue, Health Assessment Questionnaire-Disability Index, 36-item Short-Form Health Survey Physical Component Summary score, PtGA Arthritis + Psoriasis, and PsA Disease Activity Score (PASDAS) was compared between the guselkumab and placebo groups using Cox regression. Logistic regression adjusting for baseline factors evaluated associations between early (W4/W8) MCII achievement and stringent response (≥%50/%70 improvement in American College of Rheumatology response criteria, cDAPSA low disease activity [LDA], PASDAS LDA, and minimal disease activity) at W24/W52 among guselkumab-randomized patients.
resultsAmong patients with highly active PsA (baseline cDAPSA = 44.1-45.0, PASDAS = 6.4-6.5), times to MCII were significantly faster for guselkumab vs. placebo (hazard ratios 1.3-2.5; P < 0.05). Across measures, at first timepoint assessed, MCII rates were significantly higher with guselkumab (Q4W/Q8W 28-68%/29-65%) vs. placebo (19-47%; both P < 0.05). Early (W4/W8) MCII with guselkumab associated with higher odds of achieving stringent responses at W24/W52 (odds ratios 1.4-17.2/1.4-5.4).
conclusionsIn a mixed PsA population, significant proportions of patients treated with guselkumab achieved early (W4/W8) MCII across clinical and PRO measures, which associated with a higher likelihood of attaining clinically relevant improvements and low levels of disease activity at W24/W52.
