Multivariate linear regression analysis for peak hs-cTnI.
| Variables | Multivariate linear regression | ||

| Percent difference (%) | 95% CI | p ∗∗∗ | |
| sV7-9 STE | 308 | 78–834 | 0.001 |
| V1-3 STD | 115 | 1–369 | 0.055 |
| Woman | −5.73 | −44.5, 52.2 | 0.671 |
| GRACE score∗ | 3.15 | −2.77, 9.42 | 0.134 |
| hs-cTnI on admission∗∗ | 11.1 | 7.47–14.9 | <0.001 |
Numbers are calculated based on multivariable linear regression. Peak hs-cTnI was logarithmically transformed to approximate the normal distribution, and the exp (coefficient) − 1 was interpreted as the percent difference of the mean hs-cTnI. Models were adjusted for V1-3 STD (yes/no), sex (man or woman), GRACE score (∗per 10 unit, continuous); and hs-cTnI on admission (∗∗per 1000 n/L, continuous). p-value threshold was 0.006 after the Bonferroni correction. STE, ST-segment elevation; STD, ST-segment depression; GRACE, Global Registry of Acute Coronary Events; hs-cTnI, cardiac troponin I.
