BACKGROUND Interaction in clinical trials presents challenges for design and appropriate sample size estimation. Here we considered interaction between treatment assignment and a dichotomous prognostic factor with a continuous outcome. Our objectives were to describe differences in power and sample size requirements across alternative distributions of a prognostic factor and magnitudes of the i...
Background:Brain and Acute Leukemia Cytoplasmic (BAALC) is a gene which its expression is confined to progenitor cells; therefore, no expression has been illustrated in mature cells of bone marrow or white blood cells (WBC). In addition, high BAALC expression is associated with poor prognosis in Acute Myeloid Leukemia (AML) individuals and is considered as an important risk factor in Cyto...
abstract objectives: tumour necrosis factor α (tnfα) and lymphotoxin α (ltα) have been implicated in the pathogenesis of lymphoproliferative disorders. patients with b-cell non-hodgkin’s lymphoma (nhl) often have high serum levels of tnf which may be associated with a poor outcome. tnfα and ltα polymorphisms are known to influence expression of these cytokines and may explain the variable respo...
