Associations of sleep duration with all-cause mortality and poor quality of dying. a Sleep duration-mortality association after minimal adjustment; b Sleep duration-poor quality of dying association after minimal adjustment; c Sleep duration-mortality association after full adjustment; d Sleep duration-poor quality of dying association after full adjustment. Solid line = hazard ratio of sleep duration (value with minimum risk as reference) for risk of all-cause mortality or odds ratio of sleep duration (value with minimum risk as reference) for risk of poor quality of dying; Dotted lines = 95% confidence interval; df, degree of freedom
