Admission hyperphosphatemia as a predictor of severity and mortality in acute pancreatitis: A 1000-patient cohort study

Figure 1 Distribution of etiological factors in acute pancreatitis. Gallstones were the most common etiology (60%), followed by hypertriglyceridemia (15%), idiopathic causes (10%), other causes (10%), and alcohol-related acute pancreatitis (5%).

Figure 2 Kaplan-Meier survival analysis showing 30-day mortality according to admission serum phosphate category. Patients with hyperphosphatemia showed a markedly lower survival probability throughout the 30-day follow-up compared with those with normophosphatemia or hypophosphatemia. The survival curves diverged early and continued to widen over time, indicating a sustained and clinically meaningful separation between groups. The difference in survival across phosphate categories was statistically significant (log-rank P < 0.001), supporting the strong prognostic value of admission hyperphosphatemia in acute pancreatitis.
