PPARA genetic variants increase the risk for cardiac pumping function reductions following acute high-altitude exposure: A self-controlled study.
Article in Molecular genetics & genomic medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundLeft cardiac pumping function determines the compensatory capacity of the cardiovascular system following acute high-altitude exposure. Variations in cardiac output (CO) at high altitude are inconsistent between individuals, and genetic susceptibility may play a crucial role. We sought to identify genetic causes of cardiac pumping function variations and describe the genotype-phenotype correlations.
methodsA total of 151 young male volunteers were recruited and transferred to Lhasa (3,700 m) from Chengdu (<500 m) by plane. Genetic information related to hypoxic signaling and cardiovascular-related pathways was collected before departure. Echocardiography was performed both before departure and 24 hr after arrival at high altitude.
resultsHere we reported that PPARA variants were closely related to high-altitude cardiac function. The variants of rs6520015 C-allele and rs7292407 A-allele significantly increased the risk for cardiac pumping function reductions following acute high-altitude exposure. In addition, the individuals carrying haplotypes in PPARA, namely, rs135538 C-allele, rs4253623 A-allele, rs6520015 C-allele and rs7292407 A-allele (C-A-C-A), suffered a 7.27-fold risk for cardiac pumping function reduction (95% CI: 2.39-22.15, p = .0006) compared with those carrying the wild-type haplotype.
conclusionsThis self-controlled study revealed that PPARA variations significantly increased the risk for cardiac pumping function reductions following acute high-altitude exposure, providing a potential predictive marker before high-altitude exposure and targets in mechanistic studies.
