a All models adjusted for date of assessment visit, age, BMI, average temperature, smoking, and employment status (random factor: participant). b Estimates expressed as a difference in cardiovascular endpoint for each SD increment in exposure. c Additionally adjusted for SBP. d Additionally adjusted for SBP and urinary creatinine. e Additionally adjusted for SBP and mean brachial diameter. f Additionally adjusted for the SBP, mean carotid diameter, and urinary creatinine.
