For ongoing results, audience may perhaps would like to look at the consistency of ordinary deviations across studies, as an example, to get reassured that conventional deviation and standard error haven't been puzzled.138
You can find generally a paucity of information describing the info extraction processes in stories of systematic testimonials.
