Following publication of the original article [1], the authors reported an error in the Results and additional supporting funding in the Funding section.

In the Results section, paragraph must read:

Compared to the patients with uterine fibroids, patients with secondary TFI showed significantly higher levels of TNF-α, IL-8, IL-6, and TGF-β1 in the serum samples, whereas the serum cytokine concentrations were statistically significant between patients with primary TFI and the control group (Table 1). Both primary and secondary TFI groups showed significantly elevated levels of TNF-α, IL-8, IL-6, and TGF-β1 in the peritoneal fluid as compared to patients with uterine fibroids (Table 2). However, physiological differences require further discussion.

We next compared the serum levels of TNF-α, IL-8, IL-6, and TGF-β1 between the primary and secondary infertility groups and found no significant differences (Table 5). The cytokine levels in peritoneal fluid samples were statistically significant in statistics but maybe not in physiologically between the primary and secondary TFI groups (Table 6).
