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 30
Text mining as a second screener 6
Increasing the rate (speed) of screening 7
Improving workflow through screening prioritisation 12
  1. Note. Some studies adopted more than one approach to workload reduction, so column total is greater than 44 studies.
