In the print version of the article listed above, there is an error in four references cited in the conclusions section. On page 2156, references 3 and 4 should be listed as 5 and 6 in the sentences “Greater improvements in glycemic control with dulaglutide were also evident in the significantly higher percentage of patients who achieved HbA1c targets of <7.0% (53 mmol/mol) and ≤6.5% (48 mmol/mol) than with sitagliptin. In addition, the results of this trial showed that the difference in glucose-lowering effects between dulaglutide and sitagliptin was sustained over a longer period of time (i.e., 52 weeks) compared with previously published trials that compared sitagliptin to a GLP-1 receptor agonist for up to 26 weeks (3,4).” On page 2156, references 5 and 6 should be listed as reference 7 in the sentence “Dulaglutide-treated patients achieved an early improvement (after 2 weeks) in fasting glucose consistent with the reported pharmacokinetic characteristics of the drug (5,6).”

The online version reflects these changes.
