The variance-stabilizing Freeman-Tukey double arcsine transform was originally proposed for inference on single proportions. Subsequently, its use has been suggested in the context of meta-analysis of proportions. Not only has some erratic behaviour been observed before, but this transform quite generally does not appear suitable for meta-analysis purposes.
