The pooled results indicated a significant association between the +49A\/G polymorphism and an increased risk of HT in all four genetic models. Furthermore, the TSA demonstrated that the evidence of this association was robust and credible. Subgroup analysis revealed a significantly higher risk of HT in Asians compared with Caucasians associated with the +49A\/G polymorphism. Surprisingly, in contrast to the results with adults, we did not find any significant association when analyzing the pediatric subgroup. For the CT60 polymorphism, a significant association with risk of HT was detected overall, and subgroup analysis revealed that this association was significant in the Asian subgroup, but not in the Caucasian subgroup. No statistically significant associations were detected in any of the investigated genetic models for the \u2212318C\/T polymorphism.
