Estimates of tumor growth rate variation and screening test sensitivity for all age groups combined. Estimates for all age groups combined, with correction of background incidence (+21%) due to increased hormone therapy use. (a) Estimated variation of tumor growth rates, illustrated by growth curves for the 5th, 25th, 50th, 75th and 95th percentiles. (b) Estimated screening test sensitivity with 95% pointwise confidence intervals.
