2. Figure 1
Adjusted total hospitalization cost by adverse event status. Total cost of hospitalization with 95% confidence limits for patients undergoing thoracentesis with and without subsequent pneumothorax and patients undergoing paracentesis with and without subsequent bleeding complications. Cost estimates are adjusted for age, sex, race, geographic region, payer type, hospital size, teaching status, urban/rural location, admission quarter, inpatient/outpatient status, transfer status, and procedure day. Difference between costs of patients with and without events were statistically significant (P < for both cohorts).
