The ABCB1 rs2032582 T allele was associated with worse PFS than the other alleles (ES = 1.46, 95% CI = 1.14–1.87, p = 0.003), while there was no significant association between the T allele or other alleles and sunitinib-induced hypertension, HFS, or OS (ES = 0.77, 95% CI = 0.46–1.29, p = 0.326; ES = 1.02, 95% CI = 0.65–1.62, p = 0.919; ES = 1.32, 95% CI = 0.85–2.05, p = 0.215). Here, ABCB1 is linked to Hypertension.
