The problem with the link you posted is they assert deaths in the womb during the third trimester are not spontaneous abortions, but rather stillbirths. Therefore, only 127 of the study participants could have had spontaneous abortions.
The study authors could have easily (mis)used the term spontaneous abortion to refer to all cases in which the pregnancy was terminated. We could reach out to the study authors for clarification. If this is the case, then there was not an 82% rate of miscarriage.
The study authors were intentionally being misleading. They included a bunch of third trimester participants (which far outnumbered the first trimester participants) in the spontaneous abortion calculation.
The fact is, from the study, 104 women out of 127 lost their baby in the first trimester. 104/127 = 82%

This is stunning and on the order of four times the average rate.
