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

Background: Chronic kidney disease (CKD) is a major condition with a substantial sociomedical and economic burden. Klotho plays a role in renal protection via its antioxidant and anti-inflammatory properties. Proteinuria is an early indicator of CKD. Although experimental studies have demonstrated the biological effects of Klotho in CKD, its clinical relevance to proteinuria remains unclear. Methods: The present study investigated the association between the A/T alleles of the Klotho gene rs650439 single-nucleotide polymorphism (SNP) and proteinuria in a general Japanese population. Clinical and genotyping data from a total of 916 community-dwelling participants (mean age = 63 years old) were analyzed. Results: Participants carrying the minor TT genotype accounted for 13.2% of the population. The prevalence of proteinuria was significantly higher in the TT group than in the AA + AT group (15.7% vs. 7.3%, P < 0.01). Logistic regression analysis showed that the TT genotype was significantly associated with proteinuria (crude odds ratio (OR) = 2.37, 95% confidence interval (CI) 1.35-4.14). This association remained significant after adjustment for age, sex, and cardiometabolic factors (adjusted OR = 2.07, 95% CI 1.14-3.77). Conclusions: These findings suggest that the TT genotype of Klotho gene rs650439 SNP may serve as a genetic marker for early renal proteinuria. Further research is required to confirm the findings.
