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
objectiveThis study aimed to ascertain the effect of secukinumab on erosion and enthesiophyte progression in psoriatic arthritis (PsA) by using high-resolution peripheral quantitative computed tomography (HR-pQCT).
methodsThis was a phase 4, double-blind, randomized, placebo-controlled trial. Patients with active PsA and ≥1 erosion in metacarpophalangeal joints (MCPJs) 2 to 4 were randomly assigned in a 1:1 ratio to subcutaneous secukinumab or placebo. HR-pQCT of MCPJs 2 to 4 were performed at baseline, week 24, and week 48. The primary outcome was the changes in the volume of erosions on MCPJs 2 to 4 measured by HR-pQCT at 24 and 48 weeks.
resultsForty patients (mean ± SD age 51.9 ± 13.4 years, 20 [50%] male, mean ± SD disease duration 4.7 ± 6.7 years) were recruited. Thirty-four patients who completed study treatment were included in the per-protocol analysis. At baseline, week 24, and week 48, the secukinumab group showed a significant reduction in erosion volume, whereas no changes were observed in the placebo group (median change in the secukinumab group -0.1 [interquartile range -0.5 to 0.0] vs 0.0 [interquartile range -0.2 to 0.4] in the placebo group, P = 0.004). A similar trend was observed for enthesiophyte volume changes in the secukinumab group, whereas no differences were noted in the placebo group (median change in the secukinumab group -0.1 [interquartile range -0.8 to 0.0] vs 0.0 [interquartile range -0.4 to 1.3] in the placebo group, P = 0.067). Generalized estimating equations results showed that the odds ratio (OR) for enthesiophyte progression in the secukinumab group was 0.264 (95% confidence interval [CI] 0.080-0.878, P = 0.030), whereas the OR for partial erosion healing in the secukinumab group was 2.882 (95% CI 1.130-7.349, P = 0.027).
conclusionSecukinumab demonstrates a potential benefit in facilitating partial erosion repair and preventing enthesiophyte progression in PsA.
