Boys with GHR d3 allele were associated with decreased odds of pre-hypertension, and ORs (95% CIs) for the additive model and dominant model were 0.791 (0.645-0.971) and 0.777 (0.609-0.990) with P-values of 0.025 and 0.042, respectively (Table 4). This evidence concerns the gene GHR and hypertensive disorder.
