Figure 1: Among all persons with diabetes in the database, the proportion of diabetes cases that were diagnosed between Sept 2019 and February 2022, by 30-day periods relative to infection with SARS-CoV-2.

This plot represents the proportion of diabetes cases in the N3C database that were diagnosed after September 2019 in persons who did not have a previous diagnosis of diabetes. Each line represents a calendar month of the pandemic. The Y axis is the proportion of all persons with SARS-CoV-2 and a DM diagnosis who received the ICD code for DM after September 2019, and the temporal relationship between the diagnoses between 180 days prior to 360 days after the SARS-Co-V-2 infection. The large peak between 8 days before and 30 days after is represented in an inset so that the top of that peak is visible without compressing the Y axis.
