For the censored probit estimations, the two instrumental variables (IVs) included in the hypertension equation—pulse rate and an indicator for cardiovascular disease (CVD) risk, denoted as 1 if the C-reactive protein (CRP) concentration in blood is over 3 mg/litre—are statistically significant in both specifications, as measured by the Wald test. This evidence concerns the gene CRP and cardiovascular disorder.
