The TG group did however show significantly different levels of liver functional parameters ( all P less than 0.05 ) and significantly higher TTP ( 4.84 + / -4.11 vs. CG : 2.54 + / -2.08 months ; t = -2.13 , P less than 0.05 ) and average survival time ( 7.05 vs. 5.15 months ; x2 = 4.24 , P = 0.039 ) .
