RAI indicates right atrial area index; RAE, right atrial enlargement; RVFAC, RV fractional area change; SBP, systolic blood pressure

RV dysfunction was classified into normal (no dysfunction), mild or moderate to severe according to the ASE criteria. The 95% confidence intervals are reported afte5 5000 iteration of the bootstrap procedure. Model were age and sex adjusted.
