  1. All coefficients reported in % terms (decimal shifted two places to the right) to increase legibility.
  2. 95% confidence interval reported for marginal effects.
  3. Year fixed effects are dummy variables for the years 2006, 2007, and 2008.
  4. “New admissions only” means that only the first inpatient observation of each unique patient ID is Included the sample.
  5. Data: Inpatient admission for T2D, Sir Run Run Shaw Hospital (Hangzhou, China) and Shandong Provincial Hospital from 2005 to 2008. Patients under 18 are excluded.
  6. Econometric model: Probit regression with dependent variable equal to 1 if patient admitted within 6 months of first diagnosis of T2D and 0 if admitted with a duration of diagnosis greater than 6 months. Categorical independent variables are italicized, so dy/dx represents the discrete change of dummy variables from 0 to 1.
