Continuous variables are represented as medians with the IQR in parenthesis. Dichotomous variables are represented as a count with the percentage in parenthesis.
*Aortic dilatation was computed for the subsample with paired aortic data in 2013–2017.
ARB, angiotensin receptor blocker; BMI, body mass index; OSA, obstructive sleep apnoea.
