Caffeine intake above 200 milligrams per day in early pregnancy increases the risk of miscarriage.

INSUFFICIENT LEANING
Recorded sources
3 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 caffeine intake above 200 milligrams per day in early pregnancy increases the risk of miscarriage?

Unclear. Two observational studies report that first-trimester caffeine intake is associated with increased risk of pregnancy loss, but neither isolates the 200 mg/day threshold in early pregnancy: one finds the 200-299 mg/day odds ratio not statistically significant, and the other finds excess risk beginning at 100 mg/day only among nonsmokers with normal-karyotype fetuses.
