It’s not quite that quantitative:

Participants were asked, “Can you chew hard food such as hard bread or apples?” with three possible response options: (1) “Yes, without difficulty”, indicating no issues with chewing hard food; (2) “Yes, but I must be careful”, reflecting some difficulty or the need to adjust chewing habits, such as taking smaller bites or chewing more slowly to avoid discomfort; and (3) “No, not at all”, indicating a complete inability to chew hard food
