Incidence of lung nodules and tumor multiplicity in CS animals identified by light microscopy.

	Control	PJ	CS	PJ + CS
Total number of animals	11	11	11	11
Number of animals with lung nodules	0	0	4	0
Mean number of lung nodules per animal	—	—	1.30 ± 0.25	—
Tumor multiplicity (mean number of lung nodules per animal/nontumor-bearing animals)	—	—	0.19	—
Tumor incidence (number of animals with lung nodules/total number of animals)	—	—	0.36	—
Mean nodular size (mm)	—	—	1.20 ± 0.29	—

Note: PJ supplementation in the CS + PJ group prevented the formation of lung nodules that were noted in CS. CS: cigarette smoke; PJ: pomegranate juice.
