Model fitting and effect of predictors (n = 10,149, events = 1,172).

For a unified presentation of all results and figures, the findings shown are for a single imputed data set (the third data set). For OSA-related variables, HRs and 95% CIs in this data set were all within 2% of coefficients pooled across five imputed data sets.aTST90SaO2 variable was transformed using restricted cubic spline transformation with 4 knots at 0.5, 4, 9, and 100 minutes.AWK, total number of awakenings in TST; bpm, beats per minute; df, degree of freedom; HR, hazard ratio; LR, likelihood ratio; PLMI, periodic limb movement index; TST90SaO2, sleep time spent with SaO2 less than 90%.
