Notes: Difference-in-differences coefficients for robustness checks that include diabetes medical controls for the base specification (columns (1) and (5)), separate year effects (columns (2)–(4) and (6)–(8)), and restricting the sample to individuals diagnosed with diabetes prior to the collapse of the cartel (columns (4) and (8)). For base and health control definitions see Table 4. Diabetes controls are the use of oral diabetes medication and the number of diabetes-related doctor visits per year. Wild cluster bootstrap p-values are reported below each coefficient.
