Standard regression coefficients (β) with SE of RA for tooth loss are presented. Tooth loss variables were entered into linear regression models after log transformation [Ln (number of missing teeth + 1)].
RA, rheumatoid arthritis; SE, standard error.

Adjusted for sex, smoking, education level, dental caries, and frequency of toothbrushing.
