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
introductionOzoralizumab (OZR) is a novel tumor necrosis factor (TNF) inhibitor that was launched in Japan for treating patients with rheumatoid arthritis (RA) who have had an inadequate response to existing therapies. This post-hoc analysis aimed to compare the efficacy of OZR administered without methotrexate (MTX) with placebo or OZR administration in combination with MTX.
methodsWe analyzed the OZR group (30 mg) in the NATSUZORA trial (non-MTX, open trial) (OZR group; n = 94) and the placebo group (MTX group; n = 75) and the 30-mg OZR group (OZR + MTX group; n = 152) in the OHZORA trial (combined MTX, double-blind trial), and the covariates were adjusted by propensity score matching. Subsequently, the American College of Rheumatology (ACR) 20/50/70 response rates from baseline to 24 or 52 weeks were compared. Furthermore, to compare longitudinal data on disease activity indicators, a mixed-effects model for repeated-measures analyses was used.
resultsComparing the OZR and MTX groups, 52 patients were matched in each group. The OZR group showed improvements in the ACR20 (OZR group, 67.3% vs. MTX group, 34.6%, p = 0.001), ACR50 (51.9% vs. 17.3%, p < 0.001), and ACR70 (26.9% vs. 11.5%, p = 0.047) response rates compared to those in the MTX group. Comparing the OZR and OZR + MTX groups, 77 patients were matched in each group. No significant difference was observed in the ACR20 response rate (OZR group, 58.4% vs. OZR + MTX group, 70.1%, p = 0.130). However, the OZR + MTX group showed higher ACR50 (44.2% vs. 62.3%, p = 0.024) and ACR70 (29.9% vs. 45.5%, p = 0.046) response rates.
conclusionOZR administration without MTX was associated with an improvement in the signs and symptoms of RA compared to placebo administration (continuation of MTX monotherapy). OZR and MTX administration showed better efficacy than OZR administration alone.
