Association between apolipoprotein E gene polymorphisms and the effects of high-intensity interval training on body composition in university students.

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
Objective: This study examined the effects of APOE gene polymorphisms on body composition changes following high-intensity interval training (HIIT) in non-athletic Han Chinese university students from plain regions and identified genetic loci associated with HIIT sensitivity. Methods: A total of 236 Han Chinese undergraduates from non-physical education majors completed a 12-week HIIT program (three sessions/week). Body composition was assessed before and after the intervention. Genomic DNA from white blood cells was genotyped using Illumina chips. Single nucleotide polymorphism (SNP) quality control and association analyses with body composition indices were performed using PLINK (v1.09) and SPSS 25.0, applying linear regression and ANOVA with least significant difference (LSD) Results: (1) Of 22 initial APOE SNPs, five passed quality control; the rs405509 locus was associated with HIIT-induced changes in body composition. (2) The GG genotype at rs405509 was associated with higher baseline BMI overall and with higher baseline weight, BMI, and waist-to-hip ratio in females than the TT genotype. (3) After training, GG carriers showed greater reductions in overall body fat than GT/TT carriers ( Conclusion: The rs405509 locus of the APOE gene is associated with body composition responses to HIIT, and female GG carriers show heightened responsiveness.
