This is the link to the US NIH update on MPNs. Like orange juice, comes in two varieties: with bits, for those who like to know about the data/ science ( labelled “for health professionals”) and smooth, for those who prefer a simplified version ( “for patients”). You can easily toggle from one to the other.

I subscribe to the service - free- and the data source is as reliable as it gets.
