Figure 2. Percentiles of Modified Mini-Mental State Examination (3MSE) scores by intervention assignment and baseline body mass index (BMI).

Percentile regression and linear regression were used to produce smoothed curves. The p value is from a test of an interaction between baseline BMI and intervention assignment from a linear regression model with adjustment for sex, race/ethnicity, education, and current age. DSE = diabetes support and education; ILI = intensive lifestyle intervention.
