A multimodal sleep intervention improves sleep quality and architecture in chronic insomnia: a prospective exploratory study.
Trial report in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Chronic insomnia is increasingly recognized as a disorder of persistent hyperarousal, and current single-modality treatments often provide limited or unsustained benefits. This study aimed to explore the feasibility, safety, and preliminary signal of benefit of a multimodal sleep intervention combining stellate ganglion block (SGB), cognitive behavioral therapy for insomnia (CBT-I), and anesthetic-assisted sleep induction. Methods: In this prospective exploratory pilot study, 30 patients with refractory chronic insomnia who showed inadequate response to conventional therapies were enrolled. The intervention consisted of SGB, CBT-I, and propofol- and dexmedetomidine-assisted sleep induction. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) at baseline and at 7 days, 1 month, 3 months, and 6 months after treatment. Objective sleep parameters were evaluated using a wearable sleep monitoring device. Repeated measures were analyzed using generalized estimating equations. Results: PSQI total and component scores were significantly reduced at all follow-up time points compared with baseline (all Conclusion: This multimodal sleep intervention showed preliminary signals of improvements in subjective sleep quality and selected objective sleep architecture parameters, suggesting feasibility and tolerability in patients with refractory chronic insomnia and appeared to be generally well tolerated. Given the exploratory single-arm design and limited sample size, randomized controlled studies are required to further evaluate efficacy, durability, and the relative contribution of individual treatment components.
