The laboratory test variables refer to their values as reported during the first 6 months after diagnosis.
Diag., diagnosis; HB, hemoglobin; LDH, lactate dehydrogenase; Lymp, lymphocytes; NA, not available; PLT, platelet; WBC, white blood cells.
∗
Because LDH normal range values varies among laboratories, we defined it as a binary variable (elevated or not elevated).
