Home-based dim light melatonin onset assessment among adults with obesity: feasibility and procedural considerations.

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.
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
Study Objectives: Dim light melatonin onset (DLMO) is the best-established marker of central circadian phase and may contribute to unraveling the role of the circadian system in obesity. This study evaluated DLMO among individuals with obesity using a home-based assessment and explored its clinical correlates and procedural variations. Method: Fifty-eight women (mean [SD] age 40.9 [7.8] years) and body mass index (41.4 [6.6] kg/m Results: DLMO was detected in 98.2% and 89.6% of participants using an individualized or a standardized threshold, respectively. DLMO correlated with SOT but not with body mass index, cardiometabolic parameters, sleep quality, or diurnal preference. A later SOT and a larger phase angle of entrainment (DLMO-SOT) correlated with younger age and with eveningness. Most procedural alternatives showed good agreement with the original methods. Conclusions: Home-based assessment yielded a high rate of detectable DLMO in women with obesity. Diurnal preference was not correlated with central circadian phase, suggesting that other factors (e.g. behavioral, sociodemographic) may be relevant in chronotype assessment in this population. We offer implications for future research including procedural variations to consider.
