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

Background: Insomnia is a common symptom of depression, and their complex, bidirectional relationship poses significant challenges for treatment. Dexmedetomidine (Dex), an α Objective: This study aimed to determine the average effective Dex dose for inducing stage N2 sleep in patients with depression-related insomnia via polysomnography (PSG), and to identify factors affecting dose variability. Methods: From April to August 2023, 91 patients with depression-related insomnia were recruited from the Center for Pain and Sleep Medicine at the Affiliated Hospital of Shandong Second Medical University. All patients received intravenous Dex infusion (diluted to 4 μg/mL and administered at 60 mL/h) under continuous PSG monitoring. The cumulative Dex dose required to induce stage N2 sleep was recorded. Clinical data were collected, and univariate and multiple linear regression analyses were performed to identify factors influencing Dex dose. Results: A total of 82 patients were included in the final analysis. The mean effective dose of Dex required to induce stage N2 sleep was 49.0 ± 16.4 μg. Multivariate regression analysis identified age (P < 0.001) and body weight (P = 0.022) as independent predictors of Dex dose, with age exerting a stronger predictive effect. Simple linear regression further demonstrated a positive association between age and Dex dose (R Conclusion: Dex could effectively induces stage N2 sleep in patients with depression-related insomnia and has a favorable safety profile, with the required dose increasing with age.
