All, As some of you know i've been trying to identify whether there are conditions other than Infections such as EBV that may be setting the stage for ME/CFS or co-exist with ME/CFS. Machine Learning suggests that Liver-related conditions may be of particular interest. I created a Questionnaire that lists a number of Conditions / Infections / Surgical Procedures and i would kindly ask you to go through it. It takes no more than a minute to do so. The Google Form can be found here : https://goo.gl/forms/oRa5ZPtgUBVnvKwF2 Thank you in advance.
