| High fQRS‐T (°) | 2.691 (1.843–3.928) | .001 | ||||
| High PLR | 1.693 (1.152–2.487) | .007 | ||||

Low fQRS‐T (°) and low PLR (group I) |
Reference | |||||
| Either high fQRS‐T (°) or high PLR (group II) |
1.422 (0.870–2.323) |
.160 | ||||
| High fQRS‐T (°) and high PLR (group III) | 3.183 (1.971–5.139) | .001 | ||||
Note: Group I: high fQRS‐T and high PLR; Group II: Either high fQRS‐T or high PLR; Group III: low fQRS‐T and low PLR.
Abbreviations: CI, confidence interval; fQRS‐T, frontal plane QRS‐T angle; HR, hazard ratio; OR, odds ratio; PLR, platelet‐to‐lymphocyte ratio.
Entered variables: age, diabetes mellitus, hyperlipidemia, three‐vessel disease, troponin, creatinine. High fQRS‐T, fQRS‐T ≥66.72°; low fQRS‐T, fQRS‐T <66.72°; high PLR, PLR ≥101.23; low PLR, PLR<101.23. Model 1 included high fQRS‐T; Model 2, high PLR; Model 3, the groups stratified by fQRS‐T and PLR values.
