“…Since the time of Labenz's report, the onset of RE after H. pylori eradication has attracted attention and many additional studies were conducted in this regard.

Laine and Sugg 6 aggregated and analyzed the results of eight double-blind prospective studies, and reported that the incidence of RE after H. pylori eradication was 4% (24/ 621 patients) in the eradication-success group and 3% (14/544 patients) in the eradication-failure group, indicating no difference in the incidence of RE between the groups.…”
