  1. Entries with no references are assumptions. U (l, u) denotes a uniform distribution with lower limit of l and upper limit of u; β (m, σ) denotes a beta distribution with mean of m and standard derivation of σ; Γ (m, σ) denotes a gamma distribution with mean of m and standard derivation of σ. Entries marked with ‘*’ indicate that the parameter has been adjusted in the model calibration process in order to generate realistic prevalences for gonorrhoea and chlamydia.
