In females out-of reproductive decades, native Yakut and you can Evenk female presented higher amounts of TSH, and lower quantities of free thyroxine in contrast to Russian feminine ( Table 5.2 ). The real difference within the free thyroxine membership between the dos organizations is actually seen to be mathematically significant. Such performance are explained by the presence regarding hypothyroidism in the step one out-of cuatro feamales in brand new native populace off Yakutia. Three-home of these instances was in fact earliest detected with this research.

Table 6.1
There’s zero mathematically factor anywhere between groups from inside the endometrial density. M-mirror was applied to evaluate the fresh new endometrium to possess mode and you will consistent laws strength.
