Epidemiology of chronic kidney disease in young patients in developing countries.
Article in World journal of nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundChronic kidney disease (CKD) is an important but under-recognized cause of morbidity in young people living in low- and middle-income countries (LMICs), where epidemiological data in this age group are limited and fragmented. LMICs, as defined by the World Bank, have a gross national income per capita between United States dollar 1136 and United States dollar 13845 (2024).
aimTo summarize the prevalence of CKD among individuals aged ≤ 25 years in LMICs and to explore sources of between-study variability.
methodsWe performed a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. PubMed, EMBASE, Cochrane Library, and Google Scholar were searched for original studies reporting CKD prevalence in LMIC populations aged 0-25 years. Study-level proportions were pooled using a random intercept logistic regression model (generalized linear mixed model) with logit transformation. Heterogeneity was quantified using
resultsNineteen studies from 17 countries (339940 participants; 96674 CKD cases) were included. The overall pooled prevalence was 11.7% (95% confidence interval: 5.5%-23.3%), with a prediction interval spanning 0.3%-84% and extreme heterogeneity (
conclusionCKD in young people in LMICs is common and highly variable, largely reflecting differences in study setting and geography, and warrants targeted early detection and surveillance strategies.
