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

Sum of columns of a data frame equal to NA when all the elements are NA
Dear list users,
let me ask you this trivial question. I worked on that for a long time, by now.
Suppose to have a data frame with NAs and to sum some columns with rowSums:
df <- data.frame(A = runif(10), B = runif(10), C = rnorm(10))
df[1, ] <- NA
rowSums(df[ , which(names(df) %in% c("A","B"))], na.rm=T)
If all the elements of the selected columns are NA, rowSums
