^aR = 0.547; R² = 0.299; adjusted R² = 0.296; p < 0.001. The variables 20–39 years, over 60 years, long distance to the hospital, and gender were excluded by stepwise regression analyses.

^bEach additional increment in outpatient department (OPD) visits was associated with a 0.014 times increase in MCMH access (p < 0.001).

^cMCMH access of the 0–19-year-old age group was 0.405 times higher than those of other age groups (p < 0.001).

^dEach additional emergency room (ER) visit was associated with a 0.054 times increase in MCMH access (p < 0.001).

^eA patient with experience of hospitalization was associated with a 0.235 times decrease in MCMH access (p < 0.001).

^fA chronic disease patient's access to MCMH was 0.131 times higher than that of a non–chronic disease patient (p = 0.020).
