Correction: A Newfound Association between MDC1 Functional Polymorphism and Lung Cancer Risk in Chinese

There are errors in the values of the fourth and sixth sentences in the Abstract. The correct fourth sentence is: We found the SNP rs4713354A>C that is located in the 5′-untranslated region of MDC1 was significantly associated with lung cancer risk in both populations (P = 0.001), with an odds ratio as 1.33(95% confidence interval = 1.14–1.55) for the rs4713354C (CA+CC) genotypes compared to the rs4713354AA genotype. The correct sixth sentence is: The gene-based analysis rested with these SNPs suggested the MDC1 as a susceptible gene for lung cancer (P = 0.057).
