The authors regret that the incorrect identification of “omega-3 arachidonic acid” published in the original manuscript [1]. This classification is incorrect as arachidonic acid is an omega-6 polyunsaturated fatty acid. From a mechanistic standpoint, this mistake might have significance, as arachidonic acid is hypothesized to play a role in inflammatory processes. We have carefully double-checked our original data and compared the fragmentation spectra and m/z referring to Metlin Database again. We are sure that the metabolite should be arachidonic acid, instead of omega-3 arachidonic acid. Given that this misclassification is made in several places within the article’s abstract and text, a correction is warranted.
Accordingly, the name “omega-3 arachidonic acid” mentioned in the following parts should be corrected as “arachidonic acid”:
-
In the results section of Abstract: “The eutopic endometrium metabolomic profile of the endometriosis patients was characterized by a significant increase in the concentration of hypoxanthine, L-arginine, L-tyrosine, leucine, lysine, inosine, omega-3 arachidonic acid, guanosine……”.
-
In the last paragraph of Introduction: “The eutopic endometrium metabolomic profile of endometriosis patients was characterized by a significant increase in the concentration of hypoxanthine, L-arginine, L-tyrosine, leucine, lysine, inosine, omega-3 arachidonic acid, guanosine……”.
-
In the first paragraph of the section with the subheading “Identification of detected metabolites” of Results: “Obviously, levels of hypoxanthine, L-arginine, L-tyrosine, leucine, lysine, inosine, omega-3 arachidonic acid, guanosine…..”
-
In the first paragraph of Discussion: “In this regard, 11 metabolites including hypoxanthine, L-arginine, L-tyrosine, leucine, lysine, inosine, omega-3 arachidonic acid, guanosine……”
