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
Patients with idiopathic membranous nephropathy (IMN) can be categorized into phospholipase A2 receptor (PLA2R)-associated and non-PLA2R-associated cases, according to serum PLA2R antibody status. The present study aimed to determine whether clinical features differed between these.A total of 89 patients with IMN were retrospectively recruited for the present study. Serum PLA2R-Ab levels were determined by time-resolved fluoroimmunoassay. Furthermore, the relationship between serum PLA2R antibody levels and their responses to immunosuppressants among patients with a complete follow-up period, which was defined as at least 1 year, was analyzed.Among these enrollees, 71 (80.0%) patients were positive for serum PLA2R antibody. Furthermore, patients with PLA2R-associated IMN had significantly higher age (with vs without, 54.31 ± 14.03 vs 46.67 ± 13.30 years old; P = .04), proteinuria (4.32 ± 1.84 vs 3.29 ± 1.90 g/d, P = .039), and serum albumin (25.33 ± 9.60 vs 31.38 ± 9.52 g/L, P = .019), but had lower serum immunoglobulin G (6.83 ± 2.89 vs 8.72 ± 2.95 g/L, P = .016) and erythrocyte sedimentation rate (47.31 ± 32.11 vs 26.33 ± 27.94, P = .013), when compared to IMN patients without PLA2R. Furthermore, IMN patients without PLA2R exhibited a better response to immunosuppressants, when compared to patients with PLA2R-associated IMN (without vs with, 66.7% vs 62.5% at 6 months and 100% vs 87.5% at 12 months), but the difference was not statistically significant.Patients with PLA2R-associated IMN had higher disease severity than IMN patients without PLA2R. Furthermore, PLA2R negative patients had a better response to immunosuppressive therapies than PLA2R-positive patients, but the difference was not statistically significant.
