Impact of intrarenal arterial lesions on prognosis of IgA nephropathy: insights from a retrospective cohort study.
Article in Renal failure, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundIgA nephropathy (IgAN) presents a challenging spectrum of outcomes, often complicated by intrarenal arterial/arteriolar lesions (IALs) in affected individuals. Despite their clinical relevance, existing criteria for classifying and assessing the severity of these lesions remain undefined. This study aimed to establish semi-quantitative assessment criteria for grading IALs and to evaluate their prognostic significance in patients with IgAN.
methodWe conducted a retrospective cohort study of 417 cases of primary IgAN in which IALs were meticulously scored in individual biopsies. Kaplan-Meier survival analysis was employed to compare the time to the renal composite endpoint between different IALs severity groups. The association between the severity of IALs and clinical outcomes was further evaluated using multivariate Cox regression models to control for potential confounders.
resultsAmong the 417 patients studied, 230 (55.2%) exhibited IALs. Kaplan-Meier curve analysis showed a higher cumulative incidence of the composite endpoint in patients with IALs (
conclusionOur findings underscore the prognostic significance of IALs in IgAN, particularly moderate to severe intimal fibrosis and hyalinosis and highlight the urgent need for novel therapeutic strategies specifically designed to mitigate the impact of IALs in high-risk IgAN patients.
