Model 1: Covariates included were age, sex; medical history (hypertension, diabetes mellitus, dyslipidaemia, coronary heart disease), and medication at discharge (antiplatelet, antilipid and antihypertension).
Model 2: Covariates included were those in Model 1+mean 24-hour SBP.
SBP, systolic blood pressure; ST-MS, sleep-trough morning surge.
