aSMs versus NSs, from exposed group; bSMs versus NSs, out of total data; cResults are (mean ± standard deviation)/95% CI.
*Significant at p < 0.05. CI = confidence interval; Hb = hemoglobin; MCV = mean corpuscle volume; NS = nonsmoker; PCV = packed cell volume; PLT = platelet; RBC = red blood cell; SM = smoker; WBC = white blood cell.
