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

Study Objectives: Prior studies have linked depression with napping, though findings remain inconsistent. Given that major depressive episodes (MDE) commonly involve sleep-wake and circadian disturbances, we hypothesized that daytime Napping during MDE reflects more pronounced sleep/circadian disruptions and a distinct clinical profile. Materials and Methods: We compared MDE patients with and without napping (MDE-NAP vs MDE), as well as unipolar and bipolar subgroups, using subjective and objective biomarkers, including actigraphy. Results: The MDE-NAP group had more frequently hypersomnia (30.6% vs 8.2% Conclusions: Daytime napping during MDE appears to identify a distinct hypersomnolence phenotype with sleep-vegetative burden, supporting the systematic assessment of napping to guide personalized sleep- and circadian-based therapeutic strategies.
