Increasing the efficiency of study selection for systematic reviews using prioritization tools and a single-screening approach

Table 2 Results of potential STOPs for prioritization

Tool	Number of screenings^a	Proportion of relevant citations: STOP after 25% mean [min–max]	Proportion of relevant citations: STOP after 50% mean [min–max]	Proportion of relevant citations: STOP after 75% mean [min–max]
EPPI	n = 10	76% [14–100%]	88% [43–100%]	93% [71–100%]
Rayyan	n = 7	53% [0–83%]	66% [0–100%]	75% [0–100%]

^aDue to technical problems (e.g., prioritization was not triggered or export of citations was omitted); in 5 screenings, prioritization was not applied as planned, affecting 1 and 4 study selection processes with EPPI Reviewer and Rayyan, respectively
