Study design and time intervals of data collection. Prediabetes outcome was assessed after ~5 years of follow-up of initially normoglycemic POP-ABC participants. Eighteen months later, POP-ABC study participants were re-screened for a newly funded extension PROP-ABC study. The present report compares the 18-month interval changes in glycemic and other measurements between participants who developed prediabetes during POP-ABC study and those who remained normoglycemic.
