Comparing pooled proportions(complication and reoperation rates) of different treatment modalities

Dear sir/madame,


Currently I am writing a meta analysis on complications and reoperations of 5 treatment modalities after an extra-articular distal radius fracture. The treatment modalities are EF, IMN, KW, VPO and PC as the golden standard. We have included 22 studies, 10 RCTs and 12 prospective studies. All examining different treatment methods. We retrieved the data out of these studies and pooled the complication and reoperation rates(n/N). Now we want to compare the pooled proportion of each treatment modality to the golden standard of PC(plaster casting). So I want to do 4 separate comparisons using the chi squared method. I looked it up online and at the meta package guide(meta is the package I used), but wasn't able to find useful information. I first posted my question onto the stats.stackexchange website but was redirected to the mailing list of r-help. I have added a picture of the most important parts of the code (not the egger's regression, funnel, trim and fill and outcome.pdf parts of it because it didn't fit). I have added the data in excel and spss file to my dropbox, and added the complete Rcode to a Word file in my dropbox as well. The links below will refer you to them as preferred by the posting guide. Hopefully someone can help me.


Thank you very much.

Dear sir/madame,


I am currently writing a meta-analysis on the complication and reoperation rates of 5 different treatment modalities after a distal radius fracture. I was able to pool the rates of the 5 different rates using R. Now I have to compare the pooled rates of the 4 treatment modalities with the golden standard separately. I though the chi squared test would be the best method. How do I do that using r. The R code I have used for the former calculation are added as a Word-file attachment.

Not an acceptable format to the listserv program. Policy is set by the host institution. Use plain text.

Your help would be highly appreciated.


Yours sincerely,


Student
