Hello,
I am medical student, writing a meta-analysis on complication and
reoperation rates after the five most common treatments of distal
radius fractures. I have been busy with the statistics for months by
my self, but find it quite hard since our classes were very basic.
Now I want to compare the treatment modalities to see if there are
significant differences. Using R I was able to synthesize the
complication rates and reoperation rates for each treatment method.
But I never had any R course and managed by trial and error, so the
code probably doesn't look that great. Someone told me I could best
model the data in one analysis using treatment as a five level
moderator in a meta-regression. Can some help me with the R code to
do this? Your help would be very much appreciated.
Thank you,
Jay
