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

Food intake is generally accepted to be regulated by the melanocortin system, however recent data suggests that mesolimbic dopaminergic neurons also influence food intake. Whether dopamine signaling is crucial for the acute effect of leptin on feeding is unknown. Using pharmacological and genetic strategies, we tested the hypothesis that the acute inhibitory effect of leptin on food intake is partially mediated by dopamine. Dopamine D2 but not D1 receptor blockade attenuated the acute hypophagic effect of leptin in fasted mice. Additionally, mice lacking the D2R (D2R KO) exhibited an attenuated response to leptin. Conversely, dopamine receptor blockade had no effect on the acute hypophagic effect of melanocortin stimulation or the hyperphagic effect of ghrelin. These findings suggest that dopaminergic pathways do not constitute a normal part of melanocortin-dependent feeding regulation and that the dopaminergic neurocircuitry typically associated with regulation of hedonic feeding likely contributes to feeding regulation by leptin.
