Multiple regression analyses.

Multiple regression analyses between red blood cells (RBC), hemoglobin (Hb), hematocrit (Ht) and homeostasis model assessment (HOMA) in normal weight (Lean, n = 725), overweight (OW, n = 688), obese (Obese, n = 423) subjects from the study population (n = 1836). *: p<0.05; **: p<0.01; ***: p<0.001. P value for F test was <0.01 in all models except for Model 1 in the Obese group. Data adjustments: Model 1: age, sex, smoking habits. Model 2: Model 1 + Body Mass Index. Model 3: Model 1 + Waist Circumference.
