Figure 2 Positive correlations in the smokers’ group. (a) There is a highly positive correlation between SI and RBC count (P=0.003, r=0.573). (b) There is a positive correlation between 8-OHDG levels and hemoglobin concentrations in the smokers’ group (r=0.521, P=.009). 8-OHDG, 8-hydroxyl-2-deoxyguanosine; HGB, hemoglobin; RBC, red blood cell; SI, smoking index.
