*Points were assigned by dividing the regression coefficients by the absolute value of the smallest coefficient in the model and rounding up to the nearest integer. A regression coefficient of 0.233 corresponded approximately to one point.
EIU, enzyme-immunoassay unit; G-17, gastrin-17; H. pylori, Helicobacter pylori; PG, pepsinogen.
