From: Machine learning algorithms for systematic review: reducing workload in a preclinical review of animal studies and reducing human screening error

Sensitivity or recall TP/(TP + FN)
Specificity TN/(TN + FP)
Precision TP/(TP + FP)
Accuracy (TP + TN)/(TP + FP + FN + TN)
WSS@95% ((TN + FN)/N) – (1.0 – 0.95)
Positive likelihood ratio (LR+) (Sensitivity)/(1-specificity)
  1. Sensitivity, specificity, precision, accuracy and WSS@95% equations from [5]. Positive likelihood ratio equation from [45]
