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

backgroundIgA nephropathy (IgAN) is one of the most common primary glomerulonephritis worldwide, and its distribution varies significantly in different regions. The prevalence and trend of its changes in different regions of China are still unclear. Therefore, this study aims to analyze kidney biopsy data to summarize the prevalence and trend of IgAN in different regions in China.

methodsThrough a systematic electronic search of PubMed, Embase, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (SinoMed), Cochrane Library, and Wanfang databases from inception to March 1, 2023. Kidney biopsy data from the different provinces, municipalities and autonomous regions were recorded and analyzed.

resultsData concerning a total of 143,176 patients with primary glomerulonephritis in 34 provinces of China were extracted from the reported kidney biopsy data and included in the final analysis set, of which 39.73% were IgAN (56,886 cases). The proportions of male and female patients were 58.67% and 41.33%, respectively. The prevalence of IgAN patients was higher in economically developed provinces and municipalities. The weighted average prevalence before 2010 and after 2010 was 40.45% and 37.97%, respectively.

conclusionsIgAN remains the most common biopsy-proven primary glomerulonephritis in China. The prevalence of IgAN was 39.73% in China, and it was higher in developed provinces and municipalities than in other areas. The weighted average prevalence of IgAN in China decreased slightly after 2010.
