Model 1: Confounders: Adjusted for age and gender. Model 2: Adjusted for age, gender and short sleep. Model 3: Adjusted for age, gender and CVD risk factors. Model 4: Adjusted for age, gender, CVD risk factors AND short sleep.
*p < 0.001.
*Contribution of short sleep: Reduction in PR (%) between model 1 and model 2.
†Contribution of CVD risk factors: Reduction in PR (%) between model 1 and model 3.
‡Contribution of both CVD risk factors and short sleep: Reduction in PR (%) between model 1and model 4.
§Contribution of short sleep independent of CVD risk factors; Difference in PR reduction (%) between model 3 and model 4.
