Thanks for the link. It appears that the study is using patients: 1043 persons with IgG, IgA, light-chain, and biclonal MGUS detected by screening and an interpretable bone marrow sample.
I have IgM MGUS with levels going up very quickly. I wanted to get a prognosis based on this calculator. https://awmrisk.com/index.html
I already have all the values except the % needed from a BMB. If I had a good way of estimating the BMB results, I would put off having the actual BMB until it was estimated to be over 10%.
I'm now guessing that since the study doesn't include any IgM people, the authors knew it wouldn't be applicable because maybe IgM people are looking at WM rather than MM.
