st: Meta-analysis of diagnostic tests
Has anybody used Stata to do a meta-analysis of diagnostic tests? Specifically, I would like to generate summary positive and negative likelihood ratios with p-values, and an associated test of heterogeneity. I am not convinced that the metan command (metan tp fn fp tn, with tp=true positive, fn=false negative, etc.), as some have suggested, produces correct results.
As a (less desirable) alternative, I believe that I can use a logit command to generate a summary sensitivity/specificity. However, I am unclear on how that would actually be coded.
Any advice on either approach would be MUCH appreciated.
Thanks very much,
