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

African Americans have a markedly higher incidence of ESRD compared with other racial groups. Two variants in the APOL1 gene, to date observed only among individuals of recent African ancestry, associate with increased risk for renal disease among African Americans. Here, we investigated whether these risk alleles also associate with age at initiation of chronic hemodialysis. We performed a cross-sectional study of 407 nondiabetic African Americans with ESRD who participated in the Accelerated Mortality on Renal Replacement (ArMORR) study, a prospective cohort of incident chronic hemodialysis patients. African Americans carrying two copies of the G1 risk allele initiated chronic hemodialysis at a mean age of 49.0 ± 14.9 years, which was significantly younger than both subjects with one copy of the G1 allele (55.9 ± 16.7 years; P = 0.014) and subjects without either risk allele (61.8 ± 17.1 years; P = 6.2 × 10(-7)). The association between the presence of the G1 allele and age at initiation of hemodialysis remained statistically significant after adjusting for sociodemographic and other potential confounders. We did not detect an association between the G2 risk allele and age at initiation of hemodialysis, but the sample size was limited. In conclusion, genetic variations in APOL1 identify African Americans that initiate chronic hemodialysis at a younger age. Early interventions to prevent progression of kidney disease may benefit this high-risk population.
