Fixed effects in the mixed effects models for changes of fasting, 1-hour, and 2-hour plasma glucose values in 112 progressors compared to 1352 nonprogressors.

	Fasting PG (mg/dL)		1-hour PG (mg/dL)		2-hour PG (mg/dL)
	Regression coefficient	SE	Regression coefficient	SE	Regression coefficient	SE

Piecewise mixed effects modeling adjusted for age and sex. Time = a continuous variable set at the year of diagnosis for progressors or at the last checkup for nonprogressors with 0; progression = a dummy variable, 1 for progressors and 0 for nonprogressors; all coefficients are significant, p < 0.001.
