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
backgroundBorderline personality disorder (BPD) is often associated with insomnia, which may contribute to a vicious cycle of reciprocal exacerbation of sleep disturbance and BPD symptoms. Online cognitive behavioral therapy for insomnia (iCBT-I) has shown promise for treating insomnia in BPD patients. This study evaluated the key determinants, underlying processes, and change mechanisms of successful implementation of guided iCBT-I in BPD patients.
methodsIn the context of our clinical trial, we conducted this mixed-method process evaluation in 30 patients with BPD and comorbid insomnia complaints (mean age 29.5 years ± 8.72) that received guided iCBT-I. Our process evaluation was guided by four dimensions of the theoretical RE-AIM framework: Reach (e.g., reason participation), Effectiveness (e.g., perceived symptom reduction), Implementation (e.g., treatment delivery), Maintenance (e.g., sustained adherence). We combined insights from quantitative patient-reported evaluation of treatment satisfaction and adherence and therapist log data, with qualitative exploration of patient experiences through in-depth interviews in a subsample of five patients.
results21 patients (70%) completed the intervention. Patients appreciated the online modality and emphasized the importance of responsive and personalized (videocall) therapist guidance and active reminders. Patients found behavioral strategies, such as fixed bedtimes and an evening winding-down routine particularly helpful, while more introspective and cognitive techniques were often perceived as challenging. Qualitative effectiveness evaluations aligned with clinical trial outcomes on BPD, insomnia and arousal-related symptoms. Finally, patients expressed a strong desire for more and well-integrated sleep treatment into regular BPD care trajectories.
conclusionsGuided iCBT-I proved a feasible and promising intervention for patients with BPD, with successful implementation contingent upon personalized guidance, focus on behavioral strategies tailored to individual needs, and solid integration into BPD care.
