Table 1 PI and AI in ZM+DENA group, DENA group and GC + DENA group

Groups	Number	PI (%, -x±s)	AI (%, -x±s)	PI/AI
ZM + DENA group	13	15.22 ± 2.17b	7.53 ± 1.61b	2.20
DENA group	7	24.97 ± 2.53	4.36 ± 1.18	5.73
GC + DENA group	11	38.69 ± 3.17b	2.52 ± 0.81b	15.40

^bP < 0.01, vs DENA group, Fisher′s exact test.
