Abstract: meta_lr does mainly two things: it can do stratified meta-analysis of individual estimates theta1 and theta2 by stratavariables, save the stratified pooled estimates and their confidence intervals in new data set and draw them in one graph; if stratified variables are not given, meta_lr draw theta1 and theta2 and their confidence interval by individual study in one graph, with or without weighting. Combined meta-analysis results are shown in star. This command is mainly used to draw graph in diagnostic test. The user provides the effect estimate as thetas (e.g., log positive likelihood ratio and log negative likelihood ratio). Likewise, the user provides the standard error of thetas. Commands meta (STB-38, sbe16) and metareg (STB-42, sbe23) must be installed before using this command.
