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
Sleep disturbances are underidentified and undertreated in oncology. To inform screening and intervention efforts at a large academic cancer center, we identified the prevalence and correlates of patient-reported sleep difficulties. This retrospective study evaluated 20,416 individuals who completed practice-based distress screening from January 2017 to June 2024. Sleep difficulties in the past 2 weeks were reported from 0 (none) to 10 (severe). Uni- and multivariable regression models evaluated the impact of sociodemographic factors (age, sex, race/ethnicity, financial concerns) and medical/psychosocial factors (cancer type/stage, time since diagnosis, distress, anxiety, depression, pain, relationship problems, tobacco and alcohol use) on clinically significant (≥5) and severe (≥7) sleep difficulties. All variables were obtained from patients' first screen, except for cancer type, stage, and diagnosis date, which were from the cancer registry. Among the sample (59% female, 78% non-Hispanic white, 49% stage I to II, mixed cancer sites), 36% reported clinically significant sleep difficulties. In a multivariable model, the strongest correlates (OR ≥ 1.35) of sleep difficulties ≥5 were as follows: age 40 to 64 (OR = 1.35), financial concerns (OR = 1.35), distress (OR = 3.06), pain (OR = 2.80), anxiety (OR = 2.31), and depression (OR = 1.69). Risk varied by cancer type, with upper gastrointestinal, genitourinary, thoracic, and hematologic cancers showing modestly higher odds. Sensitivity analyses (cutoff ≥7, within 90 days of diagnosis) showed broadly similar but not identical correlates. Sleep difficulties are prevalent and correlated with psychosocial concerns and cancer type. Future research should explore sleep trajectories and potential care pathways for patients screening positive. SIGNIFICANCE: This large, multicenter study demonstrates that sleep difficulties are highly prevalent among oncology outpatients and are strongly associated with psychosocial distress, pain, and cancer type. Routine screening can identify at-risk patients, supporting the need for integrated, multisymptom management strategies to improve outcomes in cancer care.
