March Journal Club: Pre-conception 25-hydroxyvitamin D (25(OH)D) and fecundability
This webinar discusses a community-based prospective cohort study on "Pre-conception 25-hydroxyvitamin D (25(OH)D) and fecundability". We encourage you to download the article being discussed ahead of the webinar as well as a note-taking sheet with some question prompts to consider when evaluating research methods here.
Journal Club sessions provide a critical appraisal of published research relevant to the field of Restorative Reproductive Medicine. These sessions are designed to increase providers’ competence to critically evaluate research by increasing their knowledge of the scientific method, research design, and common biases. Improvements in knowledge and competence will translate into improvements in clinician performance as they use their understanding of research to provide better care and communication to their patients and apply the results from research to clinical practise.
