Association of sleep duration and depressive symptoms with mortality in cancer survivors.
Article in BMC cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundEvidence of the association between sleep duration, depressive symptoms, and mortality in cancer survivors is limited.
methods2,111 participants from the National Health and Nutrition Examination Surveys were involved and linked to a mortality database up to 31 December 2019. Sleep duration was self-reported at baseline. Depressive symptom was assessed using the Patient Health Questionnaire (PHQ-9) and a total score of ≥ 10 is considered clinically relevant depressive symptoms. Cox proportional hazards regression model was the main statistical models.
resultsA 2% increase in all-cause mortality was found for each 1-point increase in depressive symptoms score (hazard ratio [HR], 1.02; 95% confidence interval [CI], 1.00-1.03). Compared with those patients who slept 7 h, positive associations of < 6 h (HR, 1.79; 95% CI, 1.29-2.50), 8 h (HR, 1.46; 95% CI, 1.15-1.85), and > 8 h (HR, 1.49; 95% CI, 1.09-2.05) durations with all-cause mortality were observed. In the joint analysis, cancer survivors with depressive symptoms had a higher risk of all-cause mortality when sleeping < 6 h (HR, 1.69; 95% CI, 1.09-2.62) or ≥ 8 h (HR, 1.55; 95% CI, 1.02-2.35). LIMITATIONS: Dynamics of sleep and depression data were not available.
conclusionsLong (≥ 8 h) and short (< 6 h) sleep duration was both associated with increased risks of all-cause deaths after adjusting for depressive symptoms scores. We also observed a joint effect of sleep duration and depressive symptoms. The findings may provide evidence to guide optimal sleep duration for prolonged cancer survival.
