I hope this helps. Let me know if it doesn't.

yes, you are totally right. Sorry about this. Now I manage to run it and to get a graph. however, I don't have the estimates and CI printed on the right-hand side. The only thing added in this graph was a 2nd y-axis on the right named "confint" and nothing else differed. I am not sure I will be able to send the graph attached, but I will try. Any hints? thanks!

If your current version of Stata is Version 11 or higher, then you should update -sdecode- (and -bmjcip-) to the most recent version downloadable from SSC. I hope this helps.

The first part worked very well and now I manage to include the variable labels, thanks! however, I got some problems with the 2nd part . bmjcip S_1 S_2 S_3, cformat(%8.2f) option ftrim not allowed I still tried using other cformats and even xmlsub, but none of them worked. Can you please help me? thanks!

On the y-axis I would like to include the label of the variables names and, ideally (if possible), I would like to add, on the right hand side of the graph, the ORs and 95%CI written (just as we see for the forrest plots in a meta-analysis). Having reviewed what as been written on this topic on statalist, this is what I did: logistic asdasimprov3M1 asdascalc male num_anos_escolaridade eva_total_colunaconvhighlow4 parmest, norestore eform egen axis= axis(estimate), label(parm) twoway scatter axis estimate, /// xline(1) ylab(, valuelabel angle(0)) || /// rcap min95 max95 axis, horizontal /// legend(order(1 "point estimate" /// 2 "95% conf. int.") pos(6)) /// xlabel(0(1)8) xtitle("Odds Ratio") ytitle("") My problems are: - On the y-axis I get the variables' names, but they are abbreviated names for my own use - how do I manage to put there labels - eg instead of male, I would like to have "Male gender (vs. female)" ? - Is it to possible to create a column on the right hand side of the graph where the ORs and 95%CI are written (in addition to being ploted in the graph)? If yes, how? thanks!
