Major finding: Incidence of cancer was respectively 14.69%, 21.24%, and 5.38% for the ranitidine group, the famotidine group, and the group representing the general population without use of either H2 blocker.
Study details: This cohort study drew comparisons based on medical records for 65 million people.
