Efficacy of repeated self-guided digital cognitive behavioral therapy for chronic insomnia: A pilot open-label study following a previous RCT.

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
Objective: This study aimed to assess whether a second course of digital cognitive behavioral therapy for insomnia (dCBT-I) could benefit patients with chronic insomnia who had suboptimal responses to the initial fully self-guided dCBT-I. Methods: Building on a previous randomized controlled trial (RCT), participants with an Insomnia Severity Index (ISI) score ≥8 at 6 months after completing the initial digital CBT-I therapy were invited to enroll in the second phase of the study. Among the 20 eligible participants, 9 received a second round of digital dCBT-I therapy, 6 participated in follow-up only. Primary outcomes included changes in ISI scores and ISI remission rates (defined as ISI <8). Secondary outcomes included sleep attitudes and beliefs, as well as mental health questionnaire scores. Results: Among patients who did not achieve full remission after the first course of digital CBT-I, 44.4% and 62.5% of participants experienced a reduction in their ISI scores to <8 following the second course of treatment and at the 3-month follow-up, respectively. Following the second treatment, ISI scores showed a trend of continued decrease, but no statistically significant difference was observed compared to the baseline before the second treatment ( Conclusion: The present study suggests that a second course of digital CBT-I may benefit chronic insomnia patients who initially fail to achieve ISI remission after the first round of self-guided digital CBT-I. However, larger randomized controlled trials are needed to definitively assess its effectiveness.
