Discrimination between Cases of Duodenal Ulcer and Gastritis on the Basis of Putative Virulence Factors of Helicobacter pylori

Abstract excerpt

The BabA, cagA, and vacA statuses of 827 Helicobacter pylori isolates were used in logistic regression models to discriminate duodenal ulcer from gastritis. Only BabA was a candidate for a universal virulence factor, but the low c statistic value (0.581) indicates that none of these factors were helpful in predicting the clinical presentation.
