Table 2

Multivariate-adjusted logistic regression analysis indicating odds ratios (ORs) associated with the presence of hypertension between short and long sleep durations in the selected population. In the model, short sleep was defined as sleep durations <6 hours and in Model B; long sleep was defined as sleep durations >8 hours; reference sleep was 6 to 8 hours.
