Group 1, eGFR=60–90 mL/min/1.73 m2; group 2, eGFR=30–60 mL/min/1.73 m2; group 3, eGFR <30 mL/min/1.73 m2.
The periodontal status was assessed using the CPI system. Periodontal health was transformed from the CPI score to fair (CPI score of 1, 2 or 5), moderate (CPI score of 3) or severe (CPI score of 4) periodontal status. Fair periodontal status was clinically diagnosed as gingivitis, while moderate and severe periodontal statuses were clinically diagnosed as periodontitis.
