@caro72, My experience is that you probably do not need a transplant center now. And maybe you never will. Would you consider finding a different GI?
It sounds interesting to be part of a research study. Do you mind me asking how you got involved in it? There must be some connection to a reliable research team connected with NASH/liver disease who will be available to you? How will you be monitored for your liver health during this 2 year interval?
