aMean is the model-predicted difference (baseline minus the 3- or 6-month value).
bHbA1c: glycated hemoglobin.
cIntent-to-treat (ITT) analysis (control-intervention): difference=–0.2, 95% CI –0.6 to 0.3; P=.53 (comparison between all intervention and control patients). Per-protocol (PP) analysis (control-intervention): difference=0.3, 95% CI –0.3 to 1.0; P=.29 (comparison between intervention subjects completing at least one DEAP module [answering postmodule questions] and control patients).
dITT analysis (control-intervention): difference=–0.1, 95% CI –0.7 to 0.4; P=.67. PP analysis (control-intervention): difference=0.2, 95% CI –0.6 to 1.1; P=.54.
eITT analysis (control-intervention): difference=0.3, 95% CI 0.0 to 0.7; P=.07. PP analysis (control-intervention): difference=1.0, 95% CI 0.5 to 1.4; P<.001.
fITT analysis (control-intervention): difference=0.5, 95% CI 0.1 to 0.9; P=.02. PP analysis (control-intervention): difference=1.0, 95% CI 0.5 to 1.5; P<.001.
gSBP: systolic blood pressure.
hITT analysis (control-intervention): difference=2.1, 95% CI –1.9 to 6.2; P=.30. PP analysis (control-intervention): difference=3.3, 95% CI –2.8 to 9.4; P=.28.

jDBP: diastolic blood pressure.
