Comparison of Pulmonary Metastasis

Control (n=21) Smoke (n=21) p
Micro CT Mouse* 3 (14%) 11 (52%) 0.019
Metastasis** 0.8±0.5 3.9±1.4 0.019
HE Mouse* 6 (29%) 12 (57%) 0.061
Metastasis** 0.9±0.4 3.5±1.5 0.063

Notes: *Number of mouse with pulmonary metastasis, (%), χ2 test. **Number of pulmonary metastasis per mouse, Mean±SE, u-test. Bold value indicates p<0.05, which is considered to be statistically significant.
