Table 3. Association between pulse pressure > 80 mmHg and high DMFT index score in patients on hemodialysis.

Variables	Odds ratio (95% confidence interval)	P-valuea
Age	1.074 (1.019–1.133)	0.0080
Sex (Male)	0.945 (0.336–2.662)	0.9149
High DMFT (DMFT index score ≥ 24)	3.444 (1.126–10.532)	0.0301

Additive multivariate logistic regression models adjusted for age and sex were used for these analyses in patients on HD. The association between pulse pressure > 80 mmHg and high DMFT index scores (≥ 24) remained significantly different in a subsequent logistic regression analysis adjusted for age and sex. Independent variables were age, sex, and high DMFT index score (≥ 24). The dependent variable was pulse pressure > 80 mmHg. DMFT scores: the numbers of total, decayed (DT), missing (MT), and filled (FT) teeth.
