Plot of predictions of delay to diagnosis resulting from the cross-validation analysis. Results are shown in relation to patient age at diagnosis, and are presented using our methodology (full biomarker (bio.) model; for which ∙ is the posterior expectation) with a uniform priors or b a pooled exponential survival (surv.) model in each test group and c using standard CD4 back-estimation. The diagonal black line shows the ‘expected’ diagnosis delay for a uniform prior distribution from the age of 16 to the date of diagnosis in each patient. LOESS regression curves are also shown (blue line) with 95% CI (shaded grey). The maximum true diagnosis delay in these patients is 1 year
