The study had calculated an incidence rate of myocarditis in the Ottawa region post-vaccination by dividing the number of occurrences of the heart inflammation condition over a two-month period (June and July 2021) in Ottawa (32) by the total number of vaccinations in the area (reported as 32,379 in the pre-print).

The incidence rate of myocarditis, using these figures, equates to 10 for every 10,000 doses of the vaccine.

The pre-print paper had used an incorrect figure for the number of doses administered in Ottawa over that two-month period, however.

Between the week beginning May 30 and the week starting July 25, there had been 845,930 vaccines administered in the Ottawa region, according to data published by Ottawa Public Health, which is far greater than the figure used to calculate the incidence rate (32,379) ( here ).

The denominator (total vaccines administered over a two-month period in Ottawa) used to calculate the incidence rate of myocarditis in the pre-print study was approximately 25 times bigger than the correct figure.

1. Giant nitpick w/ original tweet: A factor of 25 - not 25 orders of magnitude.

A factor of 25 means the real number is 25 times the wrong number

25 orders of magnitude means the real number is 10,000,000,000,000,000,000,000,000 (25 zeros) times the wrong number.

2. A nit that size

Truly horrifying. I can't even begin to imagine what it might be picked with.

And, that's not a nit.
That's an intergalactic difference!
The tweeter doesn't dig math, I guess.
