  1. aThe models included the control variables: number of primary school students per number of primary schools, crime rate, discomfort index calculated by temperature and humidity, hospital beds per 1000 population, and the presence or absence of medical schools
  2. bStandard Error
  3. cConfidence Intervals
  4. dRatio of number of ophthalmologists to 1000 population
  5. eRatio of number of all physicians other than ophthalmologists to 1000 population
  6. fSES composite index was created from the percent of the population with a college-level education, percent of white-collar workers, the unemployment rate, and per capita income
