LIPC and Hypertension: The meta-analysis results revealed no significant difference in the LIPC rs1800588 polymorphism between the hypertension group and non-hypertension group under all genetic models [allele model (T vs. C, OR = 0.9276, 95% CI: 0.7838–1.0979); additive model (TT vs. CC, OR = 0.7446, 95% CI: 0.3839–1.4441) and (CT vs. CC, OR = 0.9090, 95% CI: 0.7038–1.1741); recessive model (TT vs. CC + CT, OR = 0.8176, 95% CI: 0.4286–1.5597); dominant model (TT + CT vs. CC, OR = 0.8882, 95% CI: 0.6974; 1.1312)] (Fig. 2, Table 3).
