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

Leptin is a hormone produced by adipocytes that plays a crucial role in regulating energy homeostasis and body mass. Despite its close correlation with body fat, up to ∼40% of variation in plasma leptin concentration remains unexplained, allowing for the classification of a distinct "leptin phenotype." This leptin phenotype-characterized by either relatively high or relatively low leptin concentration relative to an individual's level of body fat-presents an intriguing opportunity to test whether relatively higher (compared with lower) leptin concentrations differentially affect energy expenditure, metabolic adaptation, and susceptibility to weight change in response to energy balance perturbations. To test this hypothesis, we characterized the energy expenditure and weight change response between the two leptin phenotypes (relatively high vs. low) using three distinct experimental contexts: a cross-sectional analysis (
