Data coverage for estimating prevalence of benign prostatic hyperplasia

(A) Location-years of prevalence data for benign prostatic hyperplasia. These data are combined with Bayesian priors, predictive covariates, and regional patterns to produce estimates of prevalence specific to year, age group, and location. (B) Location-years of symptom severity data for benign prostatic hyperplasia. Due to sparsity, these data were pooled to produce a single estimate of symptomatic versus asymptomatic benign prostatic hyperplasia, which is applied to year-age-location-specific estimates of overall benign prostatic hyperplasia prevalence to determine the prevalence of symptomatic benign prostatic hyperplasia on which to apply disability.
