Meta-analysis with zero values for mean and sd. Continuous data.
Hi,
I want to do a meta-analysis with count data for treatement/control cases.
Mi problem is that I need to use zero values (an informative zero value) for
the mean and standard deviation for one of the treatement, but R has a
problem: "Studies with zero values for sd.e or sd.c get no weight in
meta-analysis". I can agroup the case by Family (byvar=Family).
¿Can you help me? Thanks!

Metafor vs Meta vs Spreadsheet: wrong numbers
Hello,
I experimented the Metafor and Meta packages in the scope of replacing Excel
for meta-analysis. I performed the first working example provided in Michael
Borenstein's book "Introduction to Meta-Analysis" with Excel, Metafor and Meta.
The numbers given by my spreadsheet, which I validated from Borenstein's book,
conrespond quite closely to those given by Meta, but

divide grid.newpage into two?
Hi,
?
Is there some easy way to split the grid.newpage() into two columns? For example, how could I put the two forest plots below (meta1 and meta2) next to each other?
library(meta)
data(Olkin95)
meta1 <- metabin(event.e, n.e, event.c, n.c,data=Olkin95, subset=c(41,47,51,59),sm="RR", meth="I",studlab=author)
meta2=meta1

ordering of additional columns in forest plot in meta package
Hi,
I am trying to add additional columns to a forest plot using the meta package.
The study information and subgroup analysis plotting is handled properly.
For this output the data is ordered first by subgroup label
(rnd.subgroup1 in the example) and second decreasing size of totals
('n' in the example).
The proper ordering of this data is confirmed by the color coding

forest (meta) editing text
OK - I've been doing some work on getting a forest plot or two together for a sub-group analaysis. Thats the crucial thing - because its a sub-group analysis rather than a meta-analsysis and all the forest (meta) and forestplot (rmeta) instructions assume you are doing a meta-analysis.
I found rmeta didn't play nicely for me so I'm using the meta package with forest. Here's some

My forest plot is not fit to windows in R software
Dear Fahimeh
It would help if you also told us what package you are using as there
are several which perform forest plots. I assume it is meta.
Your plot is cropped on three side as far as I can see. What parameters
did you give to the call of the graphics device? What happens if you use
a different graphics format like pdf? Then we may be able to see where
the issue lies.

Hi
I'm conducing a meta-analysis using the meta package.
Here's a bit of code that works fine -

I would now like to control for a couple of variables (continuous and
categorical) that aren't in the equation.

Consult a local statistician. Statistics is not you think is (namely

Model studies in one analysis using treatment as a five level moderator in a meta-regression
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
