Fig. 4From: Estimation of delay to diagnosis and incidence in HIV using indirect evidence of infection datesPredictions of delay to diagnosis (Dx) against true delay from the simulation analysis without truncation. Results are presented using our methodology (for which ∙ is the posterior expectation with 95% credibility interval in grey) with a uniform priors or b a pooled exponential survival (surv.) model and c using standard CD4 back-estimation. The diagonal green line shows the line of equality for perfect predictions in each patient. LOESS regression curves are also shown (blue line) with 95% CI (shaded grey)Back to article page
