* It's 3x10 rats, there are 3 groups (placebo, Pfizer, Sinovac) with 10 rats in each of them.

* From the research article (with minor edits for space):

   Parameter   Control G.   mRNA V. G.   Inactivated V. G.      p
  ----------  -----------  -----------  ------------------  -----
  Primordial  106.70±5.33   42.40±4.96         70.10±12.04  0.001 

But the T.A. in my physics lab class would have yelled at me for hours for using too many decimals.

* > "In a small number of rats in a single study" HN should add that automatically to the title of all submissions, and then dang/tomhow just remove the few cases where that dos not apply. I'm not sure if I must add a :) or a :( at the end of the sentence.
