Error in Table

In the original publication [1], due to an editorial office error, there were mistakes in: “Table 1. The prevalence of DR from the Japanese claim database cohort; Table 2. Complications during pregnancy from Japanese claim database cohort; Table 3. The distribution of DR stage from the multicenter cohort; Table 4. DR progression ratio from multicenter cohort.” as published. “The columns of the tables were divided by mistake”. The corrected “Table 1. The prevalence of DR from the Japanese claim database cohort; Table 2. Complications during pregnancy from Japanese claim database cohort; Table 3. The distribution of DR stage from the multicenter cohort; Table 4. DR progression ratio from multicenter cohort.” appear below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
