Prediction of Severity of Acute Pancreatitis Using Total Serum Calcium and Albumin-Corrected Calcium: A Prospective Study in Tertiary Center Hospital in Nepal

Table 3

Sensitivity, specificity, predictive values, and likelihood ratios of TC and ACC for predicting progression to severe acute pancreatitis.

Factor	S (%)	Sp (%)	PPV (%)	NPV (%)	LR+	LR−
Total calcium (≤8.2 mg/dl)	96.0	54.50	49.0	96.8	2.11	0.07
Albumin-corrected calcium (≤7.72 mg/dl)	88.0	69.10	56.4	92.7	2.85	0.17

Odds ratio (OR) for patients with calcium value ≤ 8.2 mg/dl is found to be 28.8 ( value = 0.01) (95% CI: 3.6–228.1) and OR for patients with ACC value ≤ 7.72 mg/dl is found to be 16.4 ( value = 0.001) (95% CI: 4.3–62.3).
