NK cytotoxicity in the fertile control and RM group
The general linear model showed that NK cytotoxicity in the RM group was
significantly decreased, when compared to that in the control group
(P = 0.043). Moreover, NK cytotoxicity was significantly
increased along with the increase of the effector:target ratio,
regardless of whether this ratio was in the RM group or control group
(P < 0.001, Fig. 1).
