Proportional meta-analysis error

[Mrr]

When running a proportions meta-analysis to calculate the pooled prevalence, after several attempts, I could not perform it.

A message “the condition has length >1” is displayed.

Please let me know if you have any thoughts or recommendations on how to proceed.

Thanks in advance!
