Comparison of weighted deming regression of force of infection estimates by country from cumulative incidence data and seroprevalence data.
<p>Each point is weighted depending on the error in both serology and incidence estimates, represented by the size of circles (larger circles indicating greater weight, i.e. smaller error).</p
Posterior median estimates of the total force of infection from the model fitted to incidence data (model 1) and model A (as described in [13]) to age-stratified seroprevalence data (serology) from Thailand where incidence and serology data were available from the same year and location.
<p>Posterior median estimates of the total force of infection from the model fitted to incidence data (model 1) and model A (as described in [<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0004833#pntd.0004833.ref013" target="_blank">13</a>]) to age-stratified seroprevalence data (serology) from Thailand where incidence and serology data were available from the same year and location.</p

Total force of infection and corresponding R<sub>0</sub> estimates from the model fitted to the incidence data grouped by country.
<p>Each dot represents the posterior median estimate and the error bars show the 95% CrI for each dataset. The box represents the country-specific central estimate calculated by taking the mean values of the MCMC output for each country (the line and limits of the box represents the posterior median and the 95% CrI respectively). R<sub>0</sub> assumption one: complete protection acquired upon quaternary infection, assumption two: complete protection reached after secondary infection.</p

<p>Summary of cross-sectional incidence datasets identified and associated demographics.</p
Summary of estimated reporting rates showing the baseline reporting rate or probability of detecting a secondary infection (ρ), the probability of detecting a primary infection (γ1) relative to a secondary infection, and the probability of detecting a tertiary/quaternary infection (γ3) relative to a primary infection.
<p>Each point represents the posterior median estimate and the error bars show the 95% CrI for each dataset. The box represents the country-specific central estimate calculated by taking the mean values of the MCMC output for each country (the line and limits of the box represents the posterior median and the 95% CrI respectively). A single overall value of γ1 and γ3 were estimated per country.</p
