Human placentas studied after normal and abnormal pregnancies require author attention to a number of variables derived from clinical chart review. We herein provide a Table listing many of the key variables that might be confounders for clinical studies of the human placenta. As Editors for Placenta, we respectfully request our authors to cite this Technical Note in Methods of submitted papers and include the Table provided herein, and as a download in Instructions for authors, in Supplementary material for any manuscript submission related to the human placenta. This request is optional for authors and is part of an experiment we will trial for the next three years, with the goal of improving the science reported in Placenta.
