В смысле, изобретали велосипед? Лично я обсуждала не это, а вопрос, повысилось ли количество этих тромбозов после прививки.

В статье, которую Вы привели выше, есть пример аналогичного пересчета:

If we explored the temporal relationship of the 17 cases occurring within 1‐2 weeks of vaccination, then we could extrapolate by multiplying by 26 or 52 weeks to look at the rate of ITP per year if the cases are totally ‘coincidental’ . This would be approximately 39,000 to 78,000 cases of ITP per year which is not far from the estimated total baseline incidence per year.

С оговоркой:

However, it is notable that all but one of the cases identified thus far occurred after the initial dose of SARS‐CoV‐2 vaccine. One would assume that if the vaccination was unrelated to development of ITP, case occurrences would divide more evenly between the two doses. It is also likely that the actual incidence of thrombocytopenia, including mild asymptomatic cases, may be higher and go unreported.
