Table 2.
Outcomes of patients stratified by PLR quartiles.
| Outcomes | Total (n = 5577) | Quartiles of PLR | P Value | |||
|---|---|---|---|---|---|---|
| Quartile 1 (n = 1392) PLR < 104.8 | Quartile 2 (n = 1399) 104.8 ≤ PLR < 167.0 | Quartile 3 (n = 1392) 167.0 ≤ PLR < 271.0 | Quartile 4 (n = 1394) PLR ≥ 271.0 | |||
| In-hospital mortality, n (%) | 597 (10.7) | 116 (8.3) | 120 (8.6) | 168 (12.1) | 193 (13.9) | < 0.001 |
| Length of CICU stay (days) | 2.3 (1.4, 4.2) | 2.1 (1.3, 3.9) | 2.2 (1.3, 3.9) | 2.5 (1.4, 4.4) | 2.7 (1.6, 5.2) | < 0.001 |
| Length of hospital stay (days) | 6.3 (3.9, 11.1) | 5.8 (3.3, 9.8) | 5.8 (3.5, 10.3) | 6.4 (4.0, 11.1) | 7.9 (4.6, 13.1) | < 0.001 |
Continuous variables were presented as median (IQR). Categorical variables were presented as number (percentage). P values were calculated using Kruskal–Wallis test or Chi-square test to compare differences in outcomes between different PLR quartiles.
