The nomogram for the early prediction model for hypertriglyceridemia severe acute pancreatitis (HTG-SAP). Points are assigned to patients based on the value of C-reactive protein (mg/L), lactate dehydrogenase (U/L), serum calcium (mmol/L), and ascites presence (top two to five lines) by finding the appropriate points on the ‘C-reactive protein’, ‘Lactate dehydrogenase’, ‘Serum calcium’, and ‘Ascites’, and then projecting a vertical line to the ‘Points’ scale at the top line of the nomogram. Subsequently, these points are added together, and the corresponding score on the “Total Points” scale is marked. A vertical line is then projected from the ‘Total Points’ scale to the ‘Risk of HTG-SAP’
