*OR: odds ratio with 95% confidence interval; 1Age (per 10 years); 2Tumor localization (gastric cardia; gastric body; gastric antrum); 3Tumor size (≤3 cm; >3 cm and ≤5 cm; >5 cm); 4Tumor invasion (T1; T2; T3; T4); 5Survival status (Alive vs. Dead). The cases with 3.61-5.35 mtDNA copies were used as reference.
