r_g Genetic correlation, gcov genetic covariance, gcov_se standard error of genetic covariance, LDSC LD score regression, GNOVA genetic covariance analyzer, DBP diastolic blood pressure, SBP systolic blood pressure, PP pulse pressure.

*P-value was calculated for the genetic correlation in LDSC and for the genetic covariance in GNOVA, P-values are based on two-sided Wald test.
