a
Age P = age at presentation.
b
Age St = age at which we studied the patient.
c
Hg = hemoglobin.
d
Hct = hematocrit.
e
H = high; N = normal (since several independent laboratories at local institutions performed serum Epo measurement and had different normal ranges).
f
Patient 1 and patient 2 had their serum Epo measured several times; the serum Epo was high once and at normal-to-high–normal range on other occasions.
