A
indicates the percentages of DP T cells in the PBL.
B
indicates the absolute numbers of DP T cells and lymphocyte subset per μl blood. (DP T cell count/lymphocyte count).
All absolute numbers were compared by Duncan test.
*
Indicate significant differences (P < 0.05) within DP-High versus DP-Low respectively.
†
Indicate significant differences (P < 0.05) within DP-High versus DP-Middle respectively.
‡
Indicate significant differences (P < 0.05) within DP-Middle versus DP-Low, respectively.
