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

backgroundResistance training (RT) is an established intervention for increasing lean body mass (LBM), individual hypertrophic responses exhibit significant heterogeneity, largely influenced by genetic factors. This genome-wide association study (GWAS) aimed to identify novel genetic variants associated with changes in lean body mass (∆LBM) following RT and to develop a genetic predisposition score (GPS) for predicting LBM trainability.

methodsA total of 187 sedentary adults (51.3% female, mean age 21.5 ± 2 years) completed a supervised 12-week periodized RT programme. The protocol involved squats and bench presses at 70% 1-repetition maximum (5 sets × 10 repetitions; 2-min rest) performed twice weekly. ∆LBM was precisely quantified using dual-energy X-ray absorptiometry (DEXA) before and after the intervention. Genotyping was performed on venous blood-derived DNA using the Illumina Global Screening Array-24v1-0. GWAS for ∆LBM was conducted using linear regression in PLINK 1.09, adjusted for baseline LBM, body mass index (BMI), age, region and sex (genome-wide significance threshold: p < 5 × 10

resultsThe RT programme elicited significant LBM gains across the cohort (p < 0.01) accompanied by high interindividual variability (∆LBM coefficient of variation = 0.84). GWAS identified nine novel single-nucleotide polymorphisms (SNP) significantly associated with ∆LBM (p < 5 × 10

conclusionsThis study, representing the first GWAS of RT-induced LBM adaptation, successfully identified nine novel genetic variants and establishes a robust GPS that accounts for 27.7% of interindividual variation in LBM response. These findings provide foundational genetic markers crucial for deciphering the mechanisms underlying muscle hypertrophy and significantly advance the prospects for developing personalized exercise prescriptions.
