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.

Abstract

Digital cognitive behavioral therapy for insomnia (dCBT-I) has emerged as a treatment for chronic insomnia. Smart rings provide objective, wearable-derived sleep data that may complement subjective sleep diaries, but their role in monitoring treatment response remains unclear. This study evaluated the clinical effectiveness of dCBT-I with smart rings and compared subjective and wearable-derived sleep measures. In this single-arm study, individuals with insomnia completed a dCBT-I program, alongside daily sleep monitoring using a smart ring and sleep diary. Changes in clinical symptoms were analyzed, and sleep parameters were compared across the two tools. Twenty-eight participants completed the study, with significant improvements in insomnia severity (ΔISI = - 6.16, p = .011) and anxiety symptoms (ΔGAD-7 = - 2.38, p = .038). Adherence to the smart ring was higher than to sleep diaries (52.5 vs. 44.5 days, p = .002). Sleep diaries showed significant improvements in sleep parameters, which were not reflected in smart ring data. Systematic differences were observed between data sources. dCBT-I combined with smart rings improved clinical symptoms. However, smart rings did not reflect sleep improvements seen in diaries, limiting their clinical use as a standalone monitoring tool for insomnia management.Clinical trial registration Study of Efficacy of Digital Cognitive BehavioralTherapy with Wearable Device for Insomnia.
