Hello,

I am conducting meta-analysis of case series to identify the rate of complications following a surgical procedure that can be conducted in two different ways (laparoscopic vs. open). I have the following questions:
1.	Some of the case series reported zero rate of complications for the laparoscopic procedure. When I am running the analysis using 'metaan' command and random effect model, the analysis does not go through because the standard error for the case series with 'zero' rate is 'zero'. How can I include the result from the latter case series (with zero rate of complication) in the meta-analysis?
2.	In the other arm (open group), when I do the forest plot, the lower bound of the confidence interval is less than zero in some instances, how can I truncate the lower bound in the forest plot to zero?

Thanks,
MHT
