Table 4 Work-saved by algorithms employing a single reviewer approach

From: Successful incorporation of single reviewer assessments during systematic review screening: development and validation of sensitivity and work-saved of an algorithm that considers exclusion criteria and count

Algorithm Work-saved (%) a
Mean [95%CI]
Derivation Validation
1 25.2% [24.3–26.1%] 32.0% [31.4–32.7%]
2 22.2% [21.3–23.0%] 27.5% [26.8–28.1%]
3 14.8% [14.1–15.6%] 10.5% [10.1–10.9%]
4 37.7% [36.7–38.7%] 48.2% [47.5–48.9%]
5 33.6% [32.6–34.5%] 39.8% [39.1–40.5%]
  1. aWork-saved is defined as the percentage of all citations that were excluded by the algorithm without requiring a second assessment by the investigative team
