Notes. For months in which patients do not have any tests, the number of tests is recorded as zero. Column (1) includes all patients who have at least one LDL test in our time period, and column (2) includes all patients who have at least one HbA1c test in our time period. Columns (3) and (4) include all patients. Standard errors in parentheses are robust and two-way clustered at the patient and the provider-month levels.
