Tooth loss was logarithmically transformed.
CI, confidence interval.
Multivariable linear regression analysis, adjusting for body mass index, smoking status, hemoglobin A1c, and a history of insulin or hypoglycemic medication.
Sex (0: male, 1: female).
Age category (0: <60 years, 1: ≥60 years).
In the “General Characteristics” section:
The reference range for “age for women” is stated as “27.2–79.4” but should be “27.2–79.5.”
The reference range for “tooth loss for women” is stated as “0–14.3” but should be “0–14.4.”
In the “Association between Tooth Loss and CAVI” section:
The 95% CI for “CAVI and tooth loss” is stated as “0.01 to 0.6” but should be “0.01 to 0.06.”
In the “Interaction Effects of Sex, Age, and Tooth Loss” section:
The β (95% CI) for “β for interaction” is stated as “0.04 (0.02 to 0.6)” but should be “−0.05 (−0.08 to −0.02).”
