^aModel-based estimates: adjusted for outcome value at baseline, site, risk group, site*risk group interaction, treatment group, treatment group*risk group interaction, and inflator status.

TX=Treatment Group; E=Enhanced Care; U=Usual Care; HR=Risk Group.

^bEstimates at 6 and 12 months assume baseline DMQS equal to 16.

^cEstimates at 6 and 12 months assume baseline RMQ equal to 30.

^dEstimates at 6 and 12 months assume baseline RMQ components equal to 10.
