They are only addressing pregnancies that have ended in birth or death. Read the dates. It should be obvious to anyone that with about 1200 1st trimester pregnancies being studied, and 96 1st trimester miscarriages, that is solidly in the normal range. Clearly, ANY wanted pregnancy that ends in the first trimester or early in the 2nd is going to be a miscarriage. But only 96 of 1224 1st trimester mothers had miscarriages. That’s 7.8%, and within norms. It’s NOT 82%.
