Although their data is compelling, the ramifications (regarding the magnitude of spuriously beneficial benefits in the Cochrane database) are big and thus accepting this conclusion calls for mindful unbiased affirmation. The supply of the free software (MetaXL)[56] that runs the IVhet model (and all other styles for comparison) facilitates this to the investigate Group.
