TABLE 2.

Multivariate analysis on items of the GPA score for overall survival ^a .

Candidate factors	p	Odds ratio	95% CI
			Lower	Upper
Age (<50 years vs. 50–60 years vs. 60 years)	0.027	1.4	1.1	1.8
Karnofsky performance status (80–100 b , 60–70, ≤50)	0.003	1.4	1.1	1.7
Number of BM (1 b , 2–3, ≥4)	0.005	1.3	1.1	1.6
Extracranial metastasis (no, yes)	0.361	1.1	0.9	1.5

Note: The table demonstrates multivariate Cox hazard analysis of items of the GPA score. Column one shows items of the score, column two two‐sided p‐values, column three odds ratios, the last two columns state 95% CI.

^a The results of multivariate testing by Cox regression analysis of items of the GPA score ¹⁵ are shown. The first column depicts the respective candidate factor, the second one the two‐sided p‐values, the third column the respective odds ratios following 95% CI in the fourth and fifth column.

^b Indicates reference values for the respective analysis.
