I would have to know how much stevia the mice were fed before making a judgement, but in these studies, It’s usually an astronomical amount for their size,; in other words, bogus.
As far as the amount of artificial sweeteners given to the young albino rats, both male and female, the study claims: In this study, Animal equivalent dose (AED) was calculated on the basis of body surface area by multiplying the human dose (mg/kg) by the Km ratio (AED = Human dose X Km ratio) according to Nair and Jacob (2016). Km ratio was obtained from FDA draft guidelines (2005).
Makes no sense to me but maybe someone here can decipher it.
