  • Data are mean ± SD and median (range 25–75%). Follow-up time = last exam or exam at diabetes diagnosis − data of baseline exam; sample storage time = date samples were thawed and aliquoted for measurements (1 June 2001) − date of baseline exam. Pr>|t| is the result of the paired t test. 2hPG, 2-h plasma glucose.
