Erratum to the association between the ERCC1/2 polymorphisms and radiotherapy efficacy in 87 patients with non-small cell lung cancer

In the article (1) titled “the association between the ERCC1/2 polymorphisms and radiotherapy efficacy in 87 patients with non-small cell lung cancer” published in Journal of Thoracic Disease (J Thorac Dis 2021;13:3126-36. doi: 10.21037/jtd-21-755), there were some errors in the Results section.

(I) There is a typo in a confidence interval (CI) value.

Original sentence: The median PFS of patients with the G allele was 18.9 months (95% CI: 13.960–24.780), which was significantly higher than that of patients with the A allele (11.3 months, 95% CI: 8.655–14.005); the difference between the two groups was statistically significant (P=0.040).

Corrected sentence: The median PFS of patients with the G allele was 18.9 months (95% CI: 13.960–23.780), which was significantly higher than that of patients with the A allele (11.3 months, 95% CI: 8.655–14.005); the difference between the two groups was statistically significant (P=0.040).

(II) There were errors in Table 3. The corrected version of Table 3 is included below.
