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

objectiveTo evaluate evidence on the impact of sleep health on weight loss in adults with excess weight undergoing behavioral or surgical weight loss interventions.

methodsWe conducted a systematic review of randomized controlled trials and quasi-experimental studies including adults aged ≥ 18 years with BMI ≥ 25 kg/m

resultsThirty studies (13 randomized controlled trials and 17 quasi-experimental studies; 10,944 participants from 13 countries) were included. Evidence was mixed across sleep dimensions. In behavioral weight loss interventions, sleep manipulation studies suggested that sleep restriction reduced fat loss, whereas observational studies reported inconsistent associations between sleep duration and weight loss. Limited evidence suggested that greater sleep satisfaction and higher sleep efficiency may support weight loss, with approximately half of the studies reporting positive associations. Evidence for sleep regularity, timing, and alertness was sparse and inconsistent because of the small number of studies and methodological heterogeneity.

conclusionSleep satisfaction and sleep efficiency may support weight loss in behavioral interventions, whereas sleep duration shows inconsistent associations and sleep restriction may impair fat loss. Evidence for sleep regularity, timing, and alertness remains limited. High-quality experimental studies are needed to clarify the causal role of sleep health in weight loss outcomes.
