Drinking coffee relieves headaches.

INSUFFICIENT LEANING
Recorded sources
2 sources for · 0 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 drinking coffee relieves headaches?

Unclear. Two peer-reviewed items partially support the claim: one states that coffee relieves headaches through caffeine reducing cerebral blood flow, and a review notes caffeine can relieve headaches while also triggering them. Neither item settles the claim at full strength, and no retrieved item argues against it.
