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 PRs (%) between model 1 and model 2.

‡Contribution of CVD risk factors: reduction in PRs (%) between model 1 and model 3.

§Contribution of both CVD risk factors and short sleep: reduction in PRs (%) between model 1and model 4.

¶Contribution of short sleep independent of CVD risk factors; difference in PRs reduction (%) between model 3 and model 4.
