Hi Michele,

If your version of Stata will support "midas" from ssc, it is a more uptodate version.  It is fairly common to encounter high I2 in a meta-analysis of diagnostic studies, keeping in mind these statistical tests were primarily designed with controlled trials in mind.  I would suggest the help file for midas and some recent papers in the field.  Hope this helps.

Sincerely,
Eddie

I used metandi and metandiplot command and seems to work correctly  I had a nice graph but in the outline report, the table seems confused do to the fact that  the results of the bivariate and HSROC analysis are reported together.  I'm concern also about  heterogenicity. In a "normal " meta-analysis I should check heterogenicity with I2 and Q but with HSROC analysis I' m not sure.  I also read the article of R.M: Harbord in the stat press book but I couldn't find a clear answer.
