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

Individuals who are intrinsically motivated to exercise are more likely to do so consistently. In previous research, those with at least one copy of the methionine (met) allele in the brain-derived neurotrophic factor gene (BDNF; rs6265) had greater increases in positive mood and lower perceived exertion during exercise. This study examined whether genotype for BDNF is also related to intrinsic motivation, measured by self-report during a treadmill exercise session and a free-choice behavioral measure (continuing to exercise given the option to stop) among 89 regular exercisers (age M = 23.58, SD = 3.95). Those with at least one copy of the met allele reported greater increases in intrinsic motivation during exercise and were more likely to continue exercising when given the option to stop (55 vs. 33%). Results suggest that underlying genetic factors may partially influence perceptions of inherent rewards associated with exercise and might inform the development of individually targeted interventions.
