- X ± SEM; n = 20 subjects per group. Lymphocytes are expressed both as percentages of lymphocyte number and as absolute values. Two-way repeated-measures ANOVA was performed to discriminate among the effects of age (A; p < 0.05), nutritional treatment (N; p < 0.05) and their interaction (I; p < 0.05).
- As no significant interaction was found, comparison of marginal means was carried out, which indicated a significant effect of age on the absolute number (in 109/L) of CD4-CD45RA (young: 0.54 ± 0.04 vs elderly: 0.26 ± 0.04) and on percentage of CD4-CD45RA (young: 24.9 ± 1.1 vs elderly: 14.5 ± 1.3) and CD4-CD45RO (young: 30.5 ± 1.1: vs elderly: 35.1 ± 1.3).
