T cell and humoral predictors of “Unimpaired” phenotype.

aThe indicated β-value, odds ratios, and P-values were calculated by logistic regression analysis (in step-wise backward models). Out of 112 immune parameters (see text) entered in the analysis, data shown were 9 T cell and humoral parameters that were significant in the last regression step. Covariates entered in the analysis were age, gender, and body mass index.bT cell parameters refer to combined measurement of cell frequency, and corresponding GMFI/MFI values for CD16, CD56, CD57, CD158a, and NKG2A for the indicated CD4 or CD8 subset.
