This is a series of eight introductory slidecasts about using the GRADE approach to grade the evidence in systematic reviews and create a ‘Summary of findings’ (SoF) table. The slidecasts were prepared and narrated by Holger Schünemann and Nancy Santesso from the Department of Health Research Methods, Evidence, and Impact (formerly "Clinical Epidemiology and Biostatistics"), McMaster University, Hamilton, Canada.
