(A): meal care, (B): food prescription. Data were analyzed using mixed effect modeling. The coefficients of oral care and number of functional teeth were positive. However, the coefficients of the interaction between oral care and number of functional teeth were negative. All coefficients for hospitalization for pneumonia were not statistically significant.
