Table 2 The number of studies implicitly or explicitly addressing screening workload problems (n= 44)

From: Using text mining for study identification in systematic reviews: a systematic review of current approaches

Workload reduction approach

Number of studies

Reducing number needed to screen


Text mining as a second screener


Increasing the rate (speed) of screening


Improving workflow through screening prioritisation


  1. Note. Some studies adopted more than one approach to workload reduction, so column total is greater than 44 studies.
