Authors may well only report that “pertinent†information had been extracted from Each individual included study with very little specifics of the processes employed for info extraction. It may be valuable for readers to understand no basics matter whether a systematic evaluate’s authors produced, a priori or not, a data extraction variety, no matter whether multiple types were utilised, the number of queries, if the variety was pilot tested, and who done the extraction.
