Objective evaluation of major depressive disorder using sleep electroencephalography measured by an in-home portable one-channel device: a preliminary study.
Article in Sleep & breathing = Schlaf & Atmung, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeDecreased delta and increased alpha wave activity during sleep may be specific pathophysiological features of major depressive disorder; however, their usefulness as biomarkers remains unclear. We examined the use of mean alpha and delta wave power value indices during sleep to identify major depressive disorder using a portable electroencephalography device.
methodsWe compared the mean alpha and delta wave power value indices of six unmedicated patients with major depressive disorder and seven age- and sex-matched healthy controls using a portable electroencephalography device in this case-controlled study.
resultsThe ratio of the mean alpha power values for the non-rapid and rapid eye movement periods was significantly lower in the major depressive disorder group (1.3 ± 0.2) than in the healthy group (2.3 ± 0.6; P = 0.004). The ratio of the mean delta power values for the non-rapid eye movement and rapid eye movement periods did not differ between groups but negatively correlated significantly with the Hamilton Rating Scale for Depression score (r = -0.784, P = 0.002). The area under the receiver operating characteristic curve (95% confidence interval) of the mean alpha power ratio for non-rapid eye movement and rapid eye movement periods for distinguishing the two groups was 0.93 (0.78-1.00), and both sensitivity and specificity exceeded 85% at a cut-off value ≤ 1.71.
conclusionThe alpha- and delta-related power value indices may capture different aspects of major depressive disorder pathology.
