( 1997 ), evaluating 29 patients for 180 days preceding the 1‐year post‐transplant exam, showed a highly significant inverse correlation ( p = 0.005 in univariate analysis) between CD4 + T cell counts and total infection score (i.e., frequency and severity) but not with CD8 + T cell numbers, B cell numbers, serum immunoglobulin levels, or delayed hypersensitivity responses.
