Incidence model using the prevalence estimates of monoclonal gammopathy of undetermined significance (MGUS), the rate of MGUS progression to multiple myeloma or related malignant neoplasm (δ2), and the death rates (λ1-λ3) as inputs to calculate the incidence (δ1).

4. FIGURE 3
Rate of conversion from monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma by the age of the patient. This figure shows the estimated yearly progression of MGUS in patients by current age and M-spike size for a joint fit of men and women. Separate fits of the male and female cohorts were also performed but gave a small increase in the goodness of fit (P=.31).

Fitted vs observed prevalence of monoclonal gammopathy of undetermined significance per 100,000 population by age and sex. The solid line corresponds to a smoothing spline fit and the dashed line to a linear fit with one knot. Circles represent the observed age- and sex-specific prevalence rates from the prevalence cohort.
