Unfortunately there has been a bug in the TSA program when calculating the required information size for continuous outcomes and we have now published a new amended version. In the former version the required information size was calculated twice as large as it should be in a fixed- as well as in a random-effects TSA. We apologize for the inconvenience this may cause and urge you to download the new version from the TSA homepage and redo your analyses.

The required information size for dichotomous outcomes has been calculated correct in the old version so there is no need to re-analyse dichotomous meta-analyses.
