Note. Hit rate, sensitivity, and specificity are expressed as percentages. WIF Screen = Word Identification Fluency screening measure; RDN = rapid digit naming; DA = dynamic assessment; RR = running records level; WIF_N Level = Level of Word Identification Fluency_Narrow at week 5; WIF_N Slope = Slope of Word Identification Fluency_Narrow over 5 weeks; WIF_B Level = Level of Word Identification Fluency_Broad at week 5; WIF_B Slope = Slope of Word Identification Fluency_Broad over 5 weeks; TN = true negatives; FN = false negatives; TP = true positives; FP = false positives; HR = Hit rate (TP + TN)/N; sensitivity = TP/(TP + FN); specificity = TN/(TN + FP); ROC = receiver operating characteristic; AUC = area under the curve. z = test for difference in AUC compared to Model 3: Extension Base Model.
