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: We aimed to study the effectiveness of CBT for sleep difficulties in patients with chronic fatigue syndrome/myalgic encephalitis (CFS/ME). Method: We conducted a retrospective cohort study at the Persistent Physical Symptoms Research and Treatment Unit, Maudsley Hospital, between 2014 and 2019. The primary outcome was sleep quality and other sleep parameters assessed by the Pittsburgh Sleep Quality Index (PSQI). The secondary assessments comprised the Chalder Fatigue Questionnaire (CFS), the Work and Social Adjustment Scale (WSAS), and the Short-Form Health Survey (SF-36). The data were gathered at baseline, discharge, and follow-up periods (3, 6, and 12 months). A paired samples t-test, repeated measures ANOVAs, and the Friedman Test were used to determine the effectiveness of CBT. A linear mixed model was employed to evaluate the effect size of CBT. Results: From all 217 participants (71.4% female; mean age = 39.42 ± 12.32 years), 85.7% experienced poor sleep quality. The associated factors of poor sleep quality at baseline included primary education/secondary education/vocational qualification (OR Conclusion: CBT had a significant positive effect on the sleep parameters. This effect persisted during a 12-month follow-up period. The results suggest CBT is an effective treatment for CFS/ME patients with sleep problems.
