Table 2 Summary of participants and oral conditions.Data is presented as mean ± standard deviation. Multiple comparisons between the robust, pre-frail, and frail groups were performed using one-way analysis of variance and Bonferroni’s modification.BMI, body mass index; NS, not significant; a, significant difference between the robust and frail groups; b, significant difference between the pre-frail and frail groups
