INSUFFICIENT LEANING

Recorded sources

0 sources for · 6 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that regular aspirin use causes stomach cancer?

Unclear. Several sources associate regular aspirin use with lower stomach cancer risk or report inconsistent evidence, and one trial found higher overall cancer incidence without stomach-specific causation. No retrieved item establishes that aspirin causes stomach cancer.
