Intra-abdominal pressure and procalcitonin for prognosis in patients with severe acute pancreatitis: An etiology-based analysis

Figure 3 Kaplan-Meier survival curves stratified by intra-abdominal pressure - procalcitonin risk. A and B: 28-day and 180-day survival curves demonstrated progressively worse outcomes with higher risk stratification (log-rank P < 0.001; high-risk vs low-risk hazard ratio = 6.8, 95% confidence interval: 3.5-13.2); C: Etiology-stratified survival of patients at high risk with the worst outcomes in the hypertriglyceridemic acute pancreatitis group (interaction P = 0.058). AP: Acute pancreatitis; HR: Hazard ratio; HTG-AP: Hypertriglyceridemic acute pancreatitis; IAP: Intra-abdominal pressure; PCT: Procalcitonin; CI: Confidence interval.
