Table 3 Definitions of performance measures for analgesic consumption prediction

From: Decision tree-based learning to predict patient controlled analgesia consumption and readjustment

Performance Measure Definition
Low Consumption Sensitivity a/(a+d+g)
Medium Consumption Sensitivity e/(b+e+h)
High Consumption Sensitivity i/(c+f+i)
Low Consumption Precision a/(a+b+c)
Medium Consumption Precision e/(d+e+f)
High Consumption Precision i/(g+h+i)
Overall Accuracy (a+e+i)/(a+b+c+d+e+f+g+h+i)
