Copy number variations in gastric cancer — multivariable models assessing age, tumor size, differentiation and lymph node metastasis
Characteristics      Copy number <3.61      Copy number >5.35
OR* (95% CI) P OR* (95% CI) P
Age1 0.80 (0.49-1.31) 0.38 0.96 (0.56-1.65) 0.89
Tumor size2 0.91 (0.43-1.92) 0.80 1.04 (0.46-2.36) 0.92
Differentiation3 3.00 (0.86-10.47) 0.08 1.56 (0.39-6.19) 0.53
Lymph node metastasis 7.63 (1.63-35.69) 0.01 4.41 (0.84-23.12) 0.08

*OR: odds ratio with 95% confidence interval; 1Age (per 10 years); 2Tumor size (≤3 cm; >3 cm and ≤5 cm; >5 cm); 3Differentiation (well or moderate; poor or undifferentiation). The cases with 3.61-5.35 mtDNA copies were used as reference.
