The size of THs is defined by the number of beds. Fewer than 31 beds, THs are considered as small. They are classified as medium from 31 to 59 beds and as large when the number of beds is equal or higher than 60. Single asterisk (*) denotes significant differences at 90%, double asterisk (**) denotes significant differences at 95% and triple asterisk (***) denotes significant differences at 99%.
PTE, pure technical efficiency; TE, technical efficiency; THs, township hospitals.
