  1. Notes: (1) IMI (Jan 01–16) means that the variable IMI was averaged from January 1 to January 16, IMI (Jan 17) means that the variable IMI took the value of January 17, and the rest may be deduced by analogy. (2) MedIndex was measured by the average of the number of hospitals, beds, and licensed physicians at the city level
