The original article [1] contains the following errors:

  1. 1)

    The ordinate scale is displayed incorrectly in Fig. 2D-F.

  2. 2)

    Fig. 3E was duplicated over Fig. 3F.

  3. 3)

    Table 3 contained data in the ‘HR’, ‘95% CI’, and ‘P-value’ columns of the ‘Adjuvant chemotherapy’ and ‘Non-chemotherapy’ rows that should have been deleted.

Transcriptional levels of PRDXs in various BrCa subclasses. The transcriptional level of PRDXs in BrCa patients with different subclasses, PRDXs mRNA was significantly downregulated (PRDX3) or upregulated (other PRDXs) in HER2-positive and triple-negative BrCa tissues compared with luminal BrCa tissues. a PRDX1. b PRDX2. c PRDX3. d PRDX4. e PRDX5. f PRDX6

Correlation between the genetic alterations of PRDXs and mRNA levels in BrCa tissues. a Oncoprint in cBioPortal database exhibited the proportion and distribution of specimens with genetic alterations in PRDXs. The Figure was cropped on the right to exclude specimens without any alterations. b-g Copy gain (gain and amplification) of PRDXs was associated with notably upregulated PRDXs mRNA levels compared with the copy-neutral (diploid) and copy-loss (shallow deletion and deep deletion) cases. b PRDX1. c PRDX2. d PRDX3. e PRDX4. f PRDX5. g PRDX6
