Prevalence of Chronic Kidney Disease in Latin America: A Systematic Review and Meta-analysis.
Article in Canadian journal of kidney health and disease, 2025. 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
Background: Chronic kidney disease (CKD) represents a global health concern, with particular significance in Latin America due to socioeconomic inequalities and heterogeneous health care systems. Objective: To determine the prevalence of CKD in Latin American populations through a systematic review with meta-analysis. Design: Systematic review and meta-analysis of observational studies following the PRISMA guidelines. Setting: Twelve Latin American countries (Argentina, Brazil, Chile, Colombia, Cuba, Ecuador, El Salvador, Haiti, Mexico, Nicaragua, Panama, and Peru). Patients: A total of 72 486 participants from 21 observational studies reporting CKD prevalence in Latin American populations. Measurements: The CKD prevalence according to Kidney Disease: Improving Global Outcomes (KDIGO) or Kidney Disease Outcomes Quality Initiative (K/DOQI) criteria, stratified by age groups (<60-65 vs ≥60-65 years), sex, CKD categories (G1-G5), and country. Methods: Systematic search in PubMed, SCOPUS, Web of Science, and EMBASE databases. Observational studies using standardized CKD diagnostic criteria were included without language restrictions. A meta-analysis was conducted using random-effects models with a Freeman-Tukey double arcsine transformation. The risk of bias was assessed using the Munn et al tool. Meta-regressions examined temporal trends and the effects of sample size. Results: The pooled CKD prevalence was 17.14% (95% confidence interval [CI] = 13.40-21.23%) with high heterogeneity (I Limitations: High between-study heterogeneity, most studies used single measurements rather than confirming chronicity, potential publication bias favoring higher prevalence studies, and limited representation from certain countries, which restricts generalizability. Conclusions: The prevalence of CKD in Latin America exhibits marked age-related differences, with consistently higher rates in older adults. These findings support the need for age-specific prevention strategies and standardized diagnostic approaches across the region. Trial registration: Not registered prospectively (limitation acknowledged).
