Bayesian emax model

WebApplication of a sigmoid E max model is described for the assessment of dose-response with designs containing a small number of doses (typically, three to six). The expanded model is a common E max model with a power (Hill) parameter applied to dose and the ED 50 parameter.

WebTo address these questions, we conducted a systematic review with Bayesian-based meta-analysis of all published aggregate data using a dose response (Emax) model. Meta-regression was used to consider the influence of potential moderators (including dose, sex, age, baseline MCarn and analysis method used) on the primary outcome.
