Table 4 Effect of one year supplementation of soy or control foods on red blood cells and related parameters

From: Soy protein supplementation does not cause lymphocytopenia in postmenopausal women

Measures Control (n = 27) Soy (n = 35)

MCH (pg) 28.9 ± 0.4 29.0 ± 0.4 +0.44 29.3 ± 0.4 29.8 ± 0.4 +2.02
MCHC (g/dl) 33.7 ± 0.2 34.3 ± 0.2 +1.81 33.6 ± 0.2 34.2 ± 0.2 +2.15

  1. Data represent least square mean ± SE. Differences were considered significant at P value < 0.05.
  2. *indicates that baseline values of the soy group were significantly different from the baseline values of the control group
  3. † signifies that final values were significantly different (P < 0.05) from their baseline values. No differences were observed between the soy and control groups when parameters where expressed as change (%) from baseline.
  4. RBC = red blood cell; Hb = hemoglobin; Hct = hematocrit; MCV = mean corpuscular volume; MCH = mean corpuscular hemoglobin; MCHC = mean corpuscular hemoglobin concentration; RDW = red cell distribution width index.
