Table 2.
Outcomes of patients stratified by SIRI quartiles.
| Outcomes | Total (n = 1,963) |
Quartiles of SIRI | P-value | |||
|---|---|---|---|---|---|---|
| Quartile 1 (n = 491) |
Quartile 2 (n = 491) |
Quartile 3 (n = 491) |
Quartile 4 (n = 490) |

| MACE, n (%) | 651 (33.2) | 115 (23.4) | 144 (29.3) | 169 (34.4) | 223 (45.5) | <0.001 |
| All-cause mortality | 311 (15.8) | 61 (12.4) | 75 (15.3) | 74 (15.1) | 101 (20.6) | 0.005 |
| Non-fatal MI | 64 (3.3) | 14 (2.9) | 14 (2.9) | 14 (2.9) | 22 (4.5) | 0.372 |
| Any revascularization | 276 (14.1) | 40 (8.2) | 55 (11.2) | 81 (16.5) | 100 (20.4) | <0.001 |
Categorical variables were presented as number (percentage). P-values were calculated using Chi-square test to compare differences in outcomes between different SIRI quartiles. SIRI, systemic inflammation response index; MACE, major adverse cardiovascular events; MI, myocardial infarction.
