Insomnia, Pain, and Pain-Related Dysfunctional Beliefs about Sleep among Patients with Cancer.
Article in Cancer research and treatment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeWe explored the reliability and validity of the Pain-related Beliefs and Attitudes about Sleep (PBAS) scale among patients with cancer. Further, we compared the usability of the PBAS scale with that of the Cancer-related Dysfunctional Beliefs and Attitudes about Sleep-14 (C-DBAS-14) among patients with cancer. MATERIALS AND
methodsThe medical records of 252 patients with cancer who visited the sleep clinic from August 1, 2023 to June 30, 2024 were retrospectively analyzed. The responses of the enrolled patients to the PBAS, C-DBAS-14, Insomnia Severity Index (ISI), and Numeric Rating Scale of pain were collected.
resultsThe internal consistency reliability of the PBAS scale was excellent (Cronbach's alpha of 0.96). Confirmatory factor analysis showed that the two-factor structure of the PBAS for patients with cancer is a good fit for the model (Comparative Fit Index, 0.99; Tucker-Lewis Index, 0.99; root mean square error of approximation, 0.14; standardized root mean square residual, 0.05). The convergent validity of the Korean version of the PBAS in patients with cancer was good, as indicated by its significant association with pain severity (r=0.63, p < 0.001), C-DBAS-14 (r=0.33, p < 0.001), and ISI (r=0.21, p < 0.01). The PBAS adequately reflected an increase in pain severity and was more effective and appropriate for capturing pain-related dysfunctional sleep beliefs than the C-DBAS-14.
conclusionThe Korean version of the PBAS showed high reliability and validity in patients with cancer, and applicability across cancer types and cancer-related beliefs.
