Threshold effect of METS-IR on SC-MI using piecewise binary logistic regression models.
| Inflection point | Group | OR (95% CI) | P for log likelihood ratio test | |
|---|---|---|---|---|
| METS-IR a | 37 | ≤ 37 | 0.966 (0.940, 0.993)* | <0.05 |
| > 37 | 1.029 (1.019, 1.038)** | |||
| METS-IR b | 3.7 | ≤ 3.7 | 0.707 (0.538, 0.928)* | <0.05 |
| > 3.7 | 1.327 (1.210, 1.456)** |
a
The OR was examined by per 1-unit increase of METS‐IR.
b
The OR was examined by per 10-unit increase of METS‐IR. Analyses was adjusted for variables included in Model 4. *P < 0.05, **P < 0.001. METS-IR, metabolic score for insulin resistance; SC-MI, subclinical myocardial injury; OR, odd ratio; CI, confidence interval.
