Study design. After a 1-week SAP run-in, patients had an automated carbohydrate (Carb) ratio adaptation and underwent AP training and run-in. They then used the AP for 4 weeks, with automated basal rate adaptations occurring at the start of each week for 3 more weeks. This same pattern (one carbohydrate adaptation followed by 3 weekly basal rate adaptations) was performed again for the second and third months of the study. Prespecified outcome weeks are shaded.
