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

backgroundTwo genetic variants in apolipoprotein L1 (APOL1) are associated with increased risk of focal segmental glomerulosclerosis as well as other glomerular phenotypes. These risk variants are common in individuals of African ancestry but absent in other racial groups. Yet, the majority of individuals with two APOL1 risk alleles [high-risk (HR) genotype] do not have renal disease. It is critical to identify environmental and secondary genetic influences that, when combined with these alleles, lead to kidney disease. In a recent study of black children with glomerular disease enrolled in the Nephrotic Syndrome Study Network (NEPTUNE) and Chronic Kidney Disease in Children Study (n = 104), we found that subjects with an HR genotype had a 4.6-fold increase in the odds of preterm birth as compared to those with a low risk (LR) genotype [odds ratio 4.6 (CI 1.4-15.5)]. There are known racial disparities in preterm birth, which itself is a known risk factor for chronic kidney disease and focal segmental glomerulosclerosis. Thus, we questioned whether an HR APOL1 genotype is associated with prematurity in the general African American population.

methodsWe analyzed two publically available genetic datasets of preterm birth in African Americans, including 867 infants and 519 mothers from the Gene Environment Association Studies (GENEVA) study of preterm delivery and 960 mothers from the Boston Medical Center genome-wide association study of preterm birth. We performed multivariable analyses testing for association between HR APOL1 and birth outcomes.

resultsIn both studies, there was no association between HR APOL1 in mothers and prematurity, gestational age or birthweight. Additionally, in the GENEVA study, we saw no association between infant HR APOL1 and prematurity, gestational age or birthweight.

conclusionFrom these data, we conclude that the previously observed association between HR APOL1 and prematurity is specific to those with glomerular disease, suggesting prematurity may act as an additional risk factor in APOL1-associated renal disease.
