conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...

Most integral endpoints of the antimicrobial effect are determined over an arbitrarily chosen time period, such as the dosing interval (tau), regardless of the actual effect duration. Unlike the tau-related endpoints, the intensity of the antimicrobial effect (I(E)) does consider its duration-from time zero to the time when bacterial counts on the regrowth curve achieve the same maximal numbers...

background: the diagnosis of pulmonary tuberculosis (ptb) is complicated and time-consuming currently. there was association of ptb with serum tumor markers. in this study we aimed to evaluate the predictive role of serum ca125, ca199 and cea as diagnostic tools for ptb. methods: this study was designed as a case-control study with 565 subjects who visited the yijishan hospital from jun to dec ...

diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. it is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function. it is also postulated that this benefit cannot be achieved when the drug is injected with higher rate...

A learning curve of a performance measure provides a graphical method with many benefits for judging classifier properties. The area under the ROC curve (AUC) is a useful and increasingly popular performance measure. In this paper, we consider the computational aspects of calculating AUC learning curves. A new method is provided for incrementally updating exact AUC curves and for calculating ap...

Allogeneic hematopoietic stem cell transplantation (AHSCT) is a major method of treatmentfor different hematologic and congenital disease. Graft versus host disease (GvHD) is a lifethreateningadverse effect of AHSCT. Cyclosporine is the most important and common agentfor GvHD prophylaxis. Because of variable and unpredictable pharmacokinetics of cyclosporinethat produces...

The area under a ROC curve (AUC) and partial area under a ROC curve (pAUC) are important summary measures useful in assessing the accuracy of a diagnostic test or a biomarker in discriminating true disease status. We consider nonparametric estimation of AUC and pAUC under a test-result-dependent sampling (TDS) design, which consists of a simple random component and a test-result-dependent compo...

The area under the ROC curve (AUC) is a widely used performance measure in machine learning. Increasingly, however, in several applications, ranging from ranking to biometric screening to medicine, performance is measured not in terms of the full area under the ROC curve but in terms of the partial area under the ROC curve between two false-positive rates. In this letter, we develop support vec...
