On page 23, Figure 1 Notes section was marked incorrectly. The correct Notes should read as follows:
Figure 1 Propensity score over time for GLP-1 versus basal insulin initiators.
Notes: Blue: insulin, red: GLP-1.
Abbreviation: GLP-1, glucagon-like peptide-1 analogs.
 
On page 24, Figure 2 Notes section was marked incorrectly. The correct Notes should read as follows:
Figure 2 Propensity score over time for DPP-4i versus sulfonylurea initiators.
Notes: Blue: sulfonylurea, red: DPP-4i.
Abbreviation: DPP-4i, dipeptidyl peptidase-4 inhibitors.
 
On Page 3 of Supplementary materials, Figure S2 caption was shown incorrectly. The correct caption should read as follows:
Figure S2 Histograms of propensity score over time. Intention-to-treat and perprotocol cohorts of all identified initiators of GLP-1 and insulin, and DPP-4i and sulfonylurea, respectively. Blue: insulin and sulfonylurea initiators, respectively. Red: GLP-1 and DPP-4i initiators, respectively.
 
Despite the above corrections, the interpretation of these figures in the published proof and the Supplementary materials was correct.
