1 · What the graph read from it

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.

2 · The registry

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

aimThe aim of this study was to explore the effect of sex on the clinicopathological features and long-term outcomes of IgAN patients.

methodsA total of 1096 adult IgAN patients were divided into male and female groups. Clinicopathological features and risk factors of IgAN patients of different genders were contrasted. The primary endpoint was the combined endpoint of a 50% reduction in estimated glomerular filtration rate (eGFR) and/or end stage renal disease (ESRD: eGFR < 15 mL/min/1.73 m

resultsIn total, 475 male patients and 621 female patients were included in this study. At baseline, male patients had higher values for blood pressure, serum creatinine, urine protein and serum uric acid, as well as lower levels of eGFR. Further analysis indicated that tubular atrophy/interstitial fibrosis (T) lesions and vascular lesions were more frequent in male patients. During the follow-up period of 40.9 ± 24.2 months, kidney survival rates of male IgAN patients were remarkably lower than those of female patients. Using multivariate Cox regression analysis, male gender was identified as an independent risk factor for poor outcomes (β = 0.384, Wald = 4.290, Exp (β) = 1.47, p = 0.038), including hypertension, low eGFR, IgM deposition, arteriosclerosis lesions and T1-T2 lesions. However, male and female patients were characterized by different risk factors.

conclusionMale patients presented with more severe clinical and pathological changes than female patients. Renal survival rates of male patients were remarkably lower than those of female patients, and male gender was identified as an independent risk factor for poor outcomes.
