Figure 3.

Correspondence analysis for the item response tendency. Subjects with high number of remaining teeth answered, “Regular attendance of dental clinic” and “Less frequently going out”. These behaviors may be the first stage of oral frailty. Subjects with small number of remaining teeth answered, “Feasible to chew hard food” and “difficult to eat hard food”. These mastication disabilities may be the progressed stage of oral frailty. Therefore, the levels of items were different by the number of remaining teeth.
