highly significantP = 2.55 × 10 −26
Interestingly, after correcting for the effect of potential confounding variables (see Materials and Methods ), we found small but highly significant positive correlations between micronucleus level and several hematological measures; the red blood cells distribution width (RDW, P = 2.55 × 10 −26 , Spearman R 2 = 0.1), the hemoglobin concentration distribution width (HDW, P = 1.63 × 10 −12 , R 2 = 0.04, Spearman), the mean cellular hemoglobin concentration (CHCM, P = 3.14 × 10 −11 , R 2 = 0.04, Spearman), and the measure of blood hemoglobin (measHGB, P = 1.88 × 10 −6 , R 2 = 0.02, Spearman).
