a Samples were taken for clinical and hematologic analysis at the same time as cytokine and immunofluorescence analysis. Hb, hemoglobin; CRP, C-reactive protein; rh-Epo, recombinant human erythropoietin; N/A, not applicable.
b P < 0.01 and c P < 0.001 for poor responders versus good responders.
d P < 0.01 and e P < 0.001 for poor responders versus normal controls.
f P < 0.001 for good responders versus normal controls.
