Data are regression estimates (95% CI) from the second step of our two-step econometric approach. Separate analyses for China Healthy Cities and China Healthy Counties. Estimates from subgroup analyses by region were also reported. First-step N represents the number of cities/counties included in the first step regression analysis (equation 1). First-step N*T represents the number of city/county-year observations included in the first step regression analysis (equation 1).
