From: Quantification of tuberculosis exposure in a high-burdened setting
Age-prevalence profiles are shown for all panels with the dark blue line giving the prevalence estimate from the model and the shading showing the model uncertainty with 95% credible intervals. The overlaid black points represent age-specific bioaerosol positive proportions taken from the data with error bars (panels E & F) derived from a binomial distribution using the exact method of Clopper and Pearson. For each analysis median point estimates of lambda (\(\lambda\)) and rho (\(\rho\)) are shown in the top-right corner. Results for the MCMC model using simulated data with plateaux prevalence of 0.1, 0.2, 0.3 and 0.4 are shown in panels (A–D) respectively. Panel (E) shows age-variable rate of exposure, with \(\lambda\) set at 0 for ages 0–10. Panel (F) shows a catalytic model without reversion.
