Table 3.

The five most common interventional procedures (other than PVB and certain specific image-guided procedures) performed in the year after the index PVB. This comparison is done on a subgroup of patients who had at least one interventional procedure prior to index PVB. *indicates a statistically significant change (p < .0001) from the year before to the year after
