Participants measured their plasma glucose (PG) levels using blood glucose meters (as plasma equivalent values of capillary whole blood glucose) at 9 time points (before breakfast, 90 minutes after the start of breakfast, before lunch, 90 minutes after the start of lunch, before dinner, 90 minutes after the start of dinner, at bedtime, at 4 am, before breakfast the following day). 9-point SMPG values after 26 weeks are presented. The endpoint was evaluated based on the data from on-treatment without ancillary treatment period, starting at the date of first dose of trial product until the follow-up visit, or the last date on trial product + 5 weeks for once daily insulin and + 6 weeks for once weekly insulin, or initiation of any diabetes treatment other than trial products and metformin +/- DPP4i, or increase of the dose of metformin or DPP4i.
