Clinical characteristics of the entire cohort, patients with organ failure, and patients without organ failure are shown in Table 3. The mean age of all enrolled patients was 47.5 ± 14.3 years. Etiological classifications of pancreatitis observed among these 208 patients included biliary tract stones (n = 97), hyperlipidemia (n = 52), alcohol abuse (n = 30), and idiopathic acute pancreatitis (IAP; n = 29), where the IAP classification was used to describe pancreatitis without an identifiable cause. None etiological classification (biliary tract stones, Spearman r208 = 0.059, P = .451; hyperlipidemia, Spearman r208 = -0.146, P = .061; alcohol abuse, Spearman r208 = 0.060, P = .446; and IAP, Spearman r208 = 0.045, P = .567) differed between patients with versus without organ failure.
