Since publication of our article [1], we have realised that we did not include the full data in Table 1 and missed the word (TOF) in the result/discussion section. We have provided here the adapted sentence and another version of the table, including all the information intended.

"Therefore, we plan to repeat this study in a larger sample size including well defined endometrial samples obtained during menstrual, follicular and secretory phase, to validate the reproducibility of SELDI-TOF MS technology in these samples and to identify the protein peaks observed after proteomic analysis, which are expensive and labour intense requiring High-performance liquid chromatography or high-pressure liquid chromatography (HPLC) and matrix assisted laser desorption ionization Time-of-Flight-Mass Spectrometry (MALDI-TOF/TOF MS)."
