A ‘risk score’ was developed on the basis of the association of nonsynonymous variants (rs16982743, rs893184 and rs4525, in SIGLEC12, A1BG and F5, respectively), with differential outcomes with β-blocker and calcium-channel blocker (CCB) treatment. One point was given for each genotype that conferred higher risk in the CCB group compared to the β-blocker group. Low risk was defined as a risk score of 0 or 1; high risk was defined as a risk score of 2 or 3. #One-sided P value based on a 1-sided hypothesis in the replication cohort.
