Adjusted odds ratio results (change from cohort A to cohort B).

Shown are the odds ratio (OR) estimates with corresponding 95% confidence intervals (CIs) for patients with skull base location (sb) and other locations (non-sb) of the tumor after 3 months of follow-up (3 m f/u). The difference between the two location groups was tested, and the p-value is reported (diff);additionally, the effect of excluding the exposure variable was tested, giving the p-value in the right-most column (drop).
