Letter to the editor on "Wnt signaling pathway in early‑ and late‑onset preeclampsia: evaluation with Dickkopf‑1 and R‑Spondin‑3 glycoproteins".

The aim of this Letter to the Editor was to report some methodological short comings in a recently published article. Issues regarding group dividing, misunderstanding of 5-min Apgar score and inconsistent findings. In conclusion, the results of this study should be interpreted with caution and further research is necessary.
