| helicobacter pylori infection and gastroesophageal reflux in a population-based study (the hunt study). | it has been suggested that helicobacter pylori infection may prevent gastroesophageal reflux, possibly through gastric atrophy. since, however, previous results are contradictory and no population-based studies are available, the relationship between h. pylori and reflux remains uncertain. the aim of this study was to investigate this relationship in a population-based, nested, case-control study. | 2007 | 17241296 |
