Evaluating of the association between ABO blood groups and coronavirus disease 2019 (COVID-19) in Iraqi patients	2020-09-11		.txt	text/plain	2554	158	56	title: Evaluating of the association between ABO blood groups and coronavirus disease 2019 (COVID-19) in Iraqi patients BACKGROUND: Susceptibility to the pandemic coronavirus disease 2019 (COVID-19) has recently been associated with ABO blood groups in patients of different ethnicities. With respect to COVID-19, recent studies have associated ABO blood groups with susceptibility to disease. In line with these finding, the present preliminary study sought to understand the genetic association of ABO blood groups with susceptibility to COVID-19 in Iraqi patients. Logistic regression analysis (adjusted for age and gender) was employed to assess the genetic association of ABO blood group with COVID-19 infection. Frequencies of A, B, AB, and O blood group phenotypes showed significant variations between COVID-19 patients (all cases, recovered, and deceased) and controls (pc value = 8.8 × 10 −4 , 0.012 and 1.5 × 10 −6 , respectively) ( Table 2 ).	./cache/cord-031726-ubt9wnf9.txt	./txt/cord-031726-ubt9wnf9.txt
