*All p value reference comparison between the study group and the preintervention group.

†Defined as ascitic fluid polymorphonuclear cell count over 250 cells per microliter.

‡Includes patient encounters where ascites was present and there was no documentation that patient had insufficient fluid to safely perform the procedure or other contraindication to the procedure.
