Multivariate analysis of association between metabolic syndrome (MetS) and its components with periodontal disease in separate models among 280 patients with diabetes mellitus
| Odds ratio (95 % confidence interval) of having periodontitis | p-value* | |
|---|---|---|
| Model I | ||

| Model II: Number of MetS additional to diabetes | ||
| 1 component | 1 | |
| 2 components | 5.73 (1.15, 28.59) | 0.03 |
| 3 components | 4.82 (1.03, 22.65) | 0.046 |
| 4 components | 10.77 (2.23, 51.95) | 0.003 |
| Model III: Individual components of MetS | ||

| Normal | 1 | |
| Increased | 1.74 (0.63, 4.79) | 0.286 |
| Blood pressure | ||
| Normal | 1 | |

| HDL | ||
| Normal | 1 | |
| Low | 1.99 (1.15, 3.46) | 0.004 |
*In the three models, the associations between periodontal disease and metabolic syndrome, individual components, and their combinations were adjusted for average PI, age, family income, residency area, smoking, teeth brushing, and number of missing teeth
