The extent to which the receiver operating char- acteristic curve bows out away from linearity is, therefore, a measure of the. “discriminability” of the situation.. Now that we have the machinery of the receiver operating characteristic curve, we can find the “optimal” threshold a. We established above that the chosen value of the thresh- old a implicitly determines a point on the receiver operating characteristic curve.

For the other variables, the cutoff values were determined as those that maxi- mized the sensitivity plus specificity total in the receiver operating characteristic curve (ROC). Then, we compared in-hospital mortality between four groups divided according to neutrophils and lym- phocytes percentages in BALF. The cutoff values of neutrophils and lym- phocytes percentage in BALF were same as above.

Development and validation of a set of patient reported outcome measures to assess effectiveness of asthma prophylaxis

tailieu.vn

The cut-off value to assess the asthma control was determined by receiver operating characteristic curve. Observa- tions made by experts and responses made by patients were incorporated to improve the clarity and relevance of the items. Criterion validity was demonstrated by significant correlation between the AC-PROM Tamil and forced expira- tory volume in one second (r = 0.66, p = 0.001).
