2.5 The scoring system for DS-TOFHLA
confusion
Because of the DS-TOFHLA being based on a MLR that was used to predict the D-TOFHLA, the scoring system for the DS-TOFHLA was assumed to be similar to that of the D-TOFHLA: inadequate level: 0–59 points, marginal level: 60–74 points, adequate level: 75–100 points [To assess the predicted scores of the DS-TOFHLA, a confusion matrix was used to illustrate the relation between the FHLs in the DS-TOFHLA and those in the D-TOFHLA.The accuracy for predicting the three FHLs was calculated. In addition, the ability of the DS-TOFHLA to correctly detect ‘low FHL’ was assessed in accordance with the procedure described by Parker et al. [
