  Figure 1. PEAR study design. ATEN indicates atenolol; HCTZ, hydrochlorothiazide; HR, heart rate; PEAR, Pharmacogenomics Evaluation of Antihypertensive Response.

  Figure 2. The overall analysis framework of the study. GWAS indicates genome‐wide association study; PEAR, Pharmacogenomics Evaluation of Antihypertensive Response; SNP, single nucleotide polymorphism.

  Figure 3. Effect of rs17117817 and rs2364349 polymorphisms on the β‐blocker HR response in whites within PEAR and PEAR‐2 studies. A, rs17117817. B, rs2364349. The box represents the values from the 25% to 75% percentile. The horizontal line represents the median. The black diamond represents the mean. The vertical line extends from the minimum to the maximum value. Each blue dot represents an individual. HR response was adjusted for age, sex, baseline HR, differences in dose, and principal components 1 and 2. Two‐sided P values represented are for the contrast of adjusted means between different genotype groups. *Meta‐analysis was performed assuming fixed effects and using inverse‐variance weighting. bpm indicates beats per minute; HR, heart rate; OR10P1, olfactory receptor family 10 subfamily p member 1; PEAR, Pharmacogenomic Evaluation of Antihypertensive Responses; SNX9, sorting nexin 9.

  Figure 4. Regional plot showing the significance of the associations of SNPs with changes in HR in response to β‐blockers used in whites. A, In olfactory receptor family 10 subfamily p member 1 (OR10P1) genetic region. B, In sorting nexin‐9 (SNX9) genetic region. HR indicates heart rate; SNP, single nucleotide polymorphism.

  Figure 5. β‐Blocker's HR response score in PEAR and PEAR‐2. HR responses were adjusted for age, sex, baseline HR, differences in dose, and principal components 1 and 2. Genetic variants were coded as follows: (A) rs17117817 (OR10P1 genetic region) T/T=2, G/T=1, G/G=zero, and (B) rs2364349 (SNX9 genetic region) G/G=2, A/G=1, A/A=zero. The box represents the values from the 25% to 75% percentile. The horizontal line represents the median. The vertical line extends from the minimum to the maximum value. Each blue dot represents an individual. bpm indicates beats per minute HR, heart rate; PEAR, Pharmacogenomic Evaluation of Antihypertensive Responses. *Meta‐analysis was performed between PEAR atenolol monotherapy, PEAR atenolol add‐on therapy, and PEAR‐2 metoprolol groups, assuming fixed effects and using inverse‐variance weighting.
