The pooled ORs revealed that MBL2 A > D gene polymorphism was not associated with TB risk in allelic contrast (D vs. A: p = 0.396; OR = 1.141, 95% CI = 0.842 to 1.546), homozygous (DD vs. AA: p = 0.190; OR = 2.592, 95% CI = 0.623 to 10.780), heterozygous (AD vs. AA: p = 0.859; OR = 0.971, 95% CI = 0.700 to 1.346), dominant (AA + AD vs. DD: p = 0.194; OR = 0.389, 95% CI = 0.094 to 1.616), and recessive (AA vs. DD + AD: p = 0.728; OR = 1.058, 95% CI = 0.770 to 1.454) genetic models (Fig. 4). The gene discussed is MBL2; the disease is Alzheimer disease.
