Binary test outcomes typically result from dichotomizing a continuous test variable, observable or latent. The effect of the threshold for test positivity on test sensitivity and specificity has been studied extensively in receiver operating characteristic (ROC) analysis. However, considerably less attention has been given to the study of the effect of the positivity threshold on the predictive...

Studies on respiratory muscle resting by negative pressure ventilation (NPV) in patients with stable COPD have given conflicting results. Probable explanations lie in criteria of patients' selection, method of NPV application, and lack of supervision of respiratory muscle rest. Thirteen hypercapnic patients with COPD were, therefore, randomly assigned to either a NPV group or a control group. T...
