Using the weighted area under the net benefit curve for decision curve analysis
BACKGROUND Risk prediction models have been proposed for various diseases and are being improved as new predictors are identified. A major challenge is to determine whether the newly discovered predictors improve risk prediction. Decision curve analysis has been proposed as an alternative to the area under the curve and net reclassification index to evaluate the performance of prediction models...

15 صفحه اولDecision curve analysis revisited: overall net benefit, relationships to ROC curve analysis, and application to case-control studies
BACKGROUND Decision curve analysis has been introduced as a method to evaluate prediction models in terms of their clinical consequences if used for a binary classification of subjects into a group who should and into a group who should not be treated. The key concept for this type of evaluation is the "net benefit", a concept borrowed from utility theory. METHODS We recall the foundations of...
متن کاملStrategies for early recognition of cutaneous melanoma—present and future
Cutaneous melanoma is a highly aggressive malignant tumor of skin melanocytes with an increasing incidence in most countries of the world, especially in the fair-skinned populations. Despite all preventive and therapeutic efforts, malignant melanoma is still the most lethal skin cancer. A delayed diagnosis results in an advanced stage and worsened prognosis. Once distant metastases are present,...
متن کاملCost-effectiveness of competing diagnostic-therapeutic strategies for visceral leishmaniasis.
Reported are the results of a formal decision analysis which facilitated the choice of the most appropriate test-treatment strategy for visceral leishmaniasis in areas where the disease is endemic. The following strategies were compared: treatment of all suspects (strategy A); testing by means of parasitological investigation followed by treatment of positives (strategy B); two-step testing by ...
