Dear NMUSERS, I wanted to investigate the dose-response relationship (Emax model) of a drug with NONMEM, based on data from literature (i.e. a meta-analysis). However, I am not quite sure how to deal with the different levels of random effects. Suppose I have 10 studies of different size where different doses were given and the response is presented as average change of a biomarker +/- standard deviation for each dose level. How would I incorporate the standard deviation of the biomarker measurements reported in each study for each dose level and how would I account for the different number of patients in the study? I would greatly appreciate your help, maybe with a NM-code snippet or reference to a paper where something similar has been done.
