Comparison of 90‐Day Functional Outcomes and Mortality for Patients With and Without VCS Using 2 Thresholds of BUN/Cr Ratio (VCS‐20 BUN/Cr Ratio >20) and (VCS‐30 BUN/Cr Ratio>30)
| VCS‐20, n=2626 | No VCS‐20, n=3345 | OR (95% CI) | aOR (95% CI) | |
|---|---|---|---|---|
| Change in NIHSS score, baseline–90 d | 7 (5–10) | 7 (5–10) | … | … |
| mRS >2, bad outcome | 37.6% | 46.6% | 1.45 (1.30–1.61) | 1.09 (0.97–1.23) |
| mRS score | 3 (1–5) | 3 (1–4) | 1.43 (1.30–1.57) | 1.09 (1.00–1.20) |
| Mortality | 19.8% | 13.8% | 1.53 (1.33–1.76) | 1.18 (1.01–1.31) |
| VCS‐30, n=462 | No VCS‐30, n=5509 | OR (95% CI) | aOR (95% CI) | |
|---|---|---|---|---|
| Change in NIHSS score, baseline–90 d | 7 (5–11) | 7 (5–10) | … | … |
| mRS >2, bad outcome | 31.5% | 43.5% | 1.67 (1.36–2.06) | 1.19 (0.95–1.50) |
| mRS score | 4 (2–5) | 3 (1–4) | 1.64 (1.38–1.95) | 1.17 (0.98–1.39) |
| Mortality | 23.7% | 15.8% | 1.65 (1.31–2.07) | 1.19 (0.93–1.52) |
aOR adjusted for Totaled Health Risks in Vascular Events score, onset‐to‐treatment time, and thrombolytic use. aOR indicates adjusted odds ratio; BUN/Cr, blood urea nitrogen/creatinine; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; OR, odds ratio; and VCS, volume contracted state.
