You could assume some distribution of ages between the lower and upper limit and then calculate its mean. Note though that what you propose is an ecological analysis - you are not looking at the effect of age but at the effect of being enrolled in a study with people of a certain average age.

*Does missing of mean age dealt for Meta-analysis in r? * Hi everyone, I am doing a meta-analysis for single proportion. During my review I found some articles that didn?t present the mean age of the study participants, some of them reported the age group. I want to do a moderator analysis (meta-regression) to find out the source of heterogeneity. I am asking your experience whether it?s possible to handle the missing mean age using missing data handling techniques. To give you some information about the data: 22 out of 69 included articles didn't report the mean age. If I am not burden you with this, please provide me supportive documents. Thank you for any help! *Sincerely, * *Yalemzewod Assefa Gelaw (Yalem)* *PhD Candidate, the University of Queensland, Australia * *Email: yalassefa at gmail.com <http://yalassefa at gmail.com/y.gelaw at uq.edu.au>* *"Change is good ... but it hurts "* [[alternative HTML version deleted]]
