Susceptibility distributions estimated from dose-response curves. a, b Dose-response curves for Wolbachia-free (Wolb⁻, in blue) and Wolbachia-carrier (Wolb⁺, in green) populations given data (dots) collected from Rio de Janeiro, Brazil (a) and Ho Chi Minh City, Vietnam (b). c, d Susceptibility distributions estimated by fitting dose-response models to the data (c Brazil; d Vietnam) as described in Methods section. Estimated shape (α) and scale (θ) parameters of the gamma distributions (maximum a posteriori probability, median and 95% credible intervals) are provided in Table 1. Highest probability moments: c, mean(Wolb⁻) = 1; variance(Wolb⁻) = 0; mean(Wolb⁺) = 6.920; variance(Wolb⁺) = 143.7; d, mean(Wolb⁻) = 1; variance(Wolb⁻) = 2.776; mean(Wolb⁺) = 1.490; variance(Wolb⁺) = 10.85
