Table 4. Multivariate analysis for factors affecting survival from diagnosis.

Risk factors	EFS			OS
	HR	95% CI	P value	HR	95% CI	P value
Age < 3 yr	0.58	0.10–3.21	0.529	0.37	0.06–2.24	0.277
Glioblastoma	2.10	0.80–5.50	0.133	1.92	0.66–5.54	0.229
Subtotal or less resection	3.95	1.19–13.18	0.025	3.09	0.84–11.37	0.089
Chemotherapy as front-line treatment	1.38	0.51–3.76	0.531	1.15	0.38–3.48	0.803

EFS = Event-free survival, OS = overall survival, HR = hazard ratio, CI = confidence interval.
