Multiple logistic regression analyses to predict mortality

	Odds ratio	95% confidence interval	P value
First model: mortality at 1 month as dependent variable
Mitochondrial DNA haplogroup JT	0.18	0.04 to 0.94	0.04
Lactic acid	1.23	1.05 to 1.44	0.01
Age	1.03	0.99 to 1.06	0. 11
Second model: mortality at 6 months as dependent variable
Mitochondrial DNA haplogroup JT	0.27	0.07 to 1.03	0.056
Lactic acid	1.29	1.07 to 1.56	0.008
Age	1.03	1.001 to 1.071	0. 04
Third model: mortality at 1 month as dependent variable
COXq/CSa	0.53	0.30 to 0.93	0.03
Lactic acid	1.17	0.99 to 1.37	0.07
Age	1.03	0.99 to 1.07	0.12
Fourth model: mortality at 6 months as dependent variable
COXq/CSa	0.56	0.34 to 0.93	0.03
Lactic acid	1.18	0.98 to 1.42	0.08
Age	1.03	1.00 to 1.07	0.052
