R help - Jun 2017 - Comparing pooled proportions(complication and reoperation rates) of different treatment modalities

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. Your help would be highly appreciated.


Yours sincerely,


Student

Probably the wrong list. R-help is concerned with R programming, not
statistics methodology questions, although the intersection can be
nonempty.

I suggest you post on stats.stackexchange.com instead, which *is*
concerned with statistics methodology questions.


Cheers,

1. You neglected to cc r-help!

2. Word files are **not** text files.

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.
