Volume 48, no. 7, p. 2424–2432, 2010. Page 2430, Fig. 2, x axis: “True positive rate (sensitivity)” should read “False-positive rate (1 – specificity).”
Page 2430, legend of Fig. 2, lines 4 and 5: “sensitivity (squares) and specificity (diamonds)” should read “sensitivity (diamonds) and specificity (squares).”
Page 2431, column 1, lines 47 to 49: “With regard to the two-way ROC curve constructed in Fig. 2b, 100% sensitivity was achieved at 40% inhibition” should read “With regard to the two-way ROC curve constructed in Fig. 2b, 60% sensitivity was achieved at 40% inhibition.”
Page 2431, column 1, lines 49 and 50: “However, the specificity at this percentage of inhibition was approximately 60%” should read “However, the specificity at this percentage of inhibition was approximately 100%.”
