Scatterplot Diagnostic-Test-Accuracy Meta Analysis (metadta, midas, metandi)

[Javier Arredondo Montero]

Good afternoon,
I would really appreciate it if someone with experience in DTA could help me. I'm trying to generate a scatterplot and a conditional probability plot similar to the ones shown in the reference and attached image, but I haven't been able to. I understand that they were made using metandi, midas, or metadta (tools I have installed and usually use without issues), but I can’t manage to reproduce them.
Could you help me, please? Thank you in advance.

Dear Javier Arredondo Montero, thank you for the post introduing meta-analysis issues. The plots you cited in #1 can be produced by using -midas-. Using pddam option to produce Fig. 4 a Predictive Values and Probability Modifying Plot, and using lrmatrix option to produce Fig. 4 b is Likelihood ratio scattergram, however, it seems that we cannot modify title and legend now. You can also read the material Dwamena, Ben A.(2007) MIDAS: Stata module for meta-analytical integration of diagnostic test accuracy studies http://fmwww.bc.edu/repec/bocode/m/midas.pdf

Thank you so much for your response and help. It was clearly a syntax error on my part—your code ran without any issues.
Best regards,
