These two tests differ in only one respect Troponyms (each of the following is one way to differ): depart; deviate; diverge; vary (be at variance with; be out of line with)
Other studies have also found that stevia may help improve cholesterol levels and blood pressure. On the negative side of things, there is one study that indicates consuming stevia in very large amounts could effect hormones because its glycosides have a similar structure to plant hormones such as gibberellin. But many herbs including ginkgo biloba also have this and if consumed in moderation is a non issue.
Stevia has been widely used in Japan for the past several decades without any apparent adverse effects. It actually has no calories and tastes up to 400 times sweeter than sugar, but it can produce a slightly bitter aftertaste. It won't raise blood sugar, and it may even help stabilize blood sugar levels. The sweeteners sound like a good idea, but I am not a fan.
