Table 3. Blood Cell Counts for GWI+ and GWI- Veterans.
Blood Cell Type | GWI+ (n = 57), Cells x103/μl | GWI- (n = 28), Cells x 103/μl | c-statistic* | p-value† |
---|---|---|---|---|
White Blood Cells | 6.54 (5.55–7.74)‡ | 5.66 (4.33–6.56) | 0.69 | 0.005 |
Lymphocytes | 1.82 (1.49–2.39) | 1.50 (1.35–1.76) | 0.70 | 0.004 |
Monocytes | 0.51 (0.42–0.66) | 0.40 (0.35–0.52) | 0.68 | 0.009 |
Neutrophils | 3.91 (3.27–4.87) | 3.29 (2.58–3.96) | 0.67 | 0.010 |
Platelets | 222 (201–259) | 205 (164–240) | 0.65 | 0.030 |
* A value of 0.50 would indicate no discrimination, 1.0 would be perfect discrimination of those with GWI.
