Ordinal logistic regression analysis of the H. pylori infection and the severity of TN types.
| C14 test | The classification of TN types, n (%) | Model 1 | Model 2 | Model 3 | |||
|---|---|---|---|---|---|---|---|
| Negative | TI-RADS ≤ 2 | TI-RADS3 | TI-RADS≥4 | OR (95% CI) | OR (95% CI) | OR (95% CI) | |
| H. pylori (−) | 18,139 (59.7%) | 1,603 (56.2%) | 5,556 (58.8%) | 416 (57.1%) | 1.00 (reference) | 1.00 (reference) | 1.00 (reference) |
| H. pylori (+) | 12,236 (40.3%) | 1,251 (43.8%) | 3,897 (41.2%) | 313 (42.9%) | 1.06 (1.02–1.11) | 1.01 (0.96–1.06) | 1.01 (0.96–1.05) |
| P value | – | – | – | – | 0.005* | 0.695 | 0.848 |
Model 1: unadjusted; Model 2: adjusted for sex, age, BMI, systolic, diastolic; Model 3: Model 2 + adjusted for TCH, TG, LDL, and HDL.
TN, thyroid nodule; C14 test, carbon-14 urea breath test; CI, confidence interval; BMI, body mass index; SP, systolic pressure; DP, diastolic pressure; TCH, total cholesterol; TG, triglyceride; LDL, low-density lipoprotein; HDL, high-density lipoprotein.
*P value is considered statistically significant.
