Fig. (2) Correlations of cellular immunity (CD4+ and CD8+ cells) with AST and ALT in HCV+/HIV- monoinfected and HCV+/HIV+ coinfected patients. Results are expressed as log(U/l) in case of AST and ALT, and as log(cel/ µ l) in case of CD4⁺ and CD8⁺. P-values correspond to the hypotheses of zero correlation.
