Abbreviations: ns, not significant; OW/OB, overweight/obese. Data were adjusted for age, sex, body mass index (BMI), treatment intensity score, and blood pressure (BP) control in multiple linear regression models. Change in left ventricular mass (LVM) and left atrial diameter (LAD) represents the amount of change in every dependent variable (LVM, LVM by height2.7 [LVM/h2.7], LVM by height1.7 [LVM/h1.7], and LAD) from a one‐unit increase in nighttime systolic BP (SBP), pulse pressure (PP), and night‐to‐day ratio. Bold values indicate significance.
