Dear,
I want to perform a meta-analysis for some studies with the interest lies
in incidence rates.
Many of them, the data on the number of positive cases and person-time are
available.
However, I have one study where the authors only reported point estimate
with its 95%CI.
How do I include this study into the meta-analysis using the *metafor *
package?
Here is an example code.
load("dat2C.RData")
datx <- subset(dat2C, point == 1)
estimS <- escalc(measure="IRLN", xi=Num, ti=py2/1000,
data=datx, slab=paste(Cite))
summary(estimS, transf=exp)[8:13]
resS <- rma( yi, vi, data=estimS, method="ML")
hetS <- cbind(round( resS$QE,1),round( resS$QEp,2), round( resS$I2))
hetS # 96%
## However, how to include this study where point estimate (Inc)
## and 95% CI (Incll = lower bound, Incul = upper bound) were reported
xx <- subset(dat2C, point==0); dim(xx)
I look forward to hearing from you.
Regards,
Thao
