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

Aerobic exercise is arguably the most metabolically demanding challenge imposed on the human body. The metabolic adaptations to exercise are complex, involving most tissues and differing substantially depending on the type, severity, and duration of exercise as well as the extent of prior training. Studies of these metabolic responses have been ongoing for decades, including the active National Institutes of Health (NIH)-supported consortium MotrPAC. Most studies have been carried out in model organisms, generally rodents or dogs. However, the metabolism of these model organisms substantially differs from humans. We therefore review here what is known specifically of human metabolism during exercise. For the sake of brevity, we focus on aerobic exercise without extensive prior training. We review methods used to reach conclusions, highlight the many remaining unknowns, and discuss questions requiring future experimental attention.
