<qa>  What is the name of the group that suggested the study of diabetes?For exploratory purposes, the data will be processed and examined in two ways.

However, because these criteria change from time to time and because we are interested to see how these biochemical values may form a new index, a second option to manipulate all these variables has been planned.
