Table 2 The Cox proportional hazards model analysis of preoperative factors for postoperative survival in patients with MSCC from NSCLC

From: Prediction of survival prognosis after surgery in patients with symptomatic metastatic spinal cord compression from non-small cell lung cancer

Factors Simple cox regression Multiple cox regression
HR (95 % CI) P HR (95 % CI) P
Preoperative ambulatory status 2.24 (1.30–3.86) 0.004 Excludeda
ECOG performance status 2.78 (1.54–5.02) <0.001 2.18 (1.15–4.16) 0.017
Number of involved vertebrae 2.46 (1.39–4.35) 0.002 2.05 (1.11–3.76) 0.021
Visceral metastases 2.29 (1.33–3.94) 0.003 2.00 (1.10–3.62) 0.022
Time developing motor deficits 3.44 (1.90–6.22) <0.001 2.70 (1.45–5.03) 0.002
