Table 2.
The association between quartile of GAR and 90-day mortality by Cox proportional-hazard regression.
| Variable | Q1, N=104 (< 20.1) |
Q2, N=105 (20.1 to < 22.6) |
Q3, N=102 (22.6 to < 25.0) |
Q4, N=103 (≥25.0) |
|---|---|---|---|---|
| 90-day mortality (%) | 14 (13.5) | 8 (7.6) | 9 (8.8) | 28 (27.2) |
| Crude, HR (95% CI) | 1.80 (0.76-4.30) | Reference | 1.17 (0.45-3.03) | 4.07 (1.86-8.93) |
| Model 1, HR (95% CI) | 1.86 (0.77-4.49) | Reference | 1.24 (0.48-3.24) | 3.98 (1.81-8.77) |
| Model 2, HR (95% CI) | 1.45 (0.55-3.78) | Reference | 1.02 (0.38-2.76) | 2.73 (1.21-6.17) |
HR, hazard ratio; CI, confidence interval.
Model 1: adjusted for age, sex and race.
Model 2: adjusted for age, sex, race, category of ICU, SAPS II, heart failure, cerebrovascular disease, renal dysfunction, mean arterial pressure, respiratory rate, SPO2, and urine output.
