| 3-mmMRI | P Value | 1-mmMRI | P Value | 1-mmMRI+DLR | |
|---|---|---|---|---|---|

↵a P value was calculated by using paired t test for depth of invasion and McNemar test for degree of contact with the intracavernous ICA. Data are mean or number of patients, and data in parentheses are 95% confidence intervals unless otherwise specified.
