Conversely, when the NYT group data from before and after treatment were compared, the Hb (9.8 ± 1.0 g/dL vs. 12.0 ± 1.0 g/dL), Ht (32.7% ± 2.1% vs. 38.2% ± 3.3%), and ferritin (median 4 ng/mL (3–10) compared with median of 19 ng/mL (10–26) significantly increased, while the CFS subscales (physical fatigue 7.1 ± 5.4 vs. 2.5 ± 2.4, affective fatigue 7.9 ± 4.1 vs. 4.9 ± 3.4, cognitive fatigue 2.8 ± 2.8 vs. 0.7 ± 1.0, overall fatigue 17.9 ± 10.2 vs. 8.1 ± 5.2) and VAS-A (56 (50–70) mm compared with median of 23 (6–48) mm) significantly decreased. This evidence concerns the gene GSTM1 and myalgic encephalomeyelitis/chronic fatigue syndrome.
