  1. Chewing ability (IRT): Self-assessed chewing ability calculated by the scores of the 3-parameter logistic model of item response theory
  2. Chewing ability (inability to chew at least one food): Self-assessed inability to chew at least one food among the 15 different types of food
  3. Self-assessed number of slightly hard foods that cannot be chewed among 3 foods
  4. Serum albumin levels were statistically significant for all of the models. Masticatory function evaluation based on IRT analysis. Inability to chew at least one food among the 15 different types of food and self-assessed number of slightly hard foods that cannot be chewed among 3 foods were all statistically significant in men. However, they were not significant in women or the total population. They were not statistically significant in the strata model (strata by sex)
