The Youden index was used to identify the optimal cut-off point on the receiver operator characteristic curve with equal weighting of sensitivity and specificity and to determine the potential reduction in antibiotic therapy in hospitalized patients.
Reticence is understandable given that the weight of historical sensitivity makes audiences uneasy about seeing such a figure in the context of entertainment.
To what extent patients can benefit from the higher statistical weighting of the sensitivity should be examined in a greater patient population.
22 This value is 'optimal' in the sense that it maximises the overall rate of correct classification in the absence of a loss function (ie, giving the same weight to errors of sensitivity and specificity).
Some related problems, such as effective sample size, the order of imputation, the behavior of weights, and sensitivity to the choice of prior distribution, are also analyzed in detail.
These interpretative methods can be divided in two types of methodologies: analysis based on the magnitude of weights and sensitivity analysis.
This method of calculating optimal cut-points gives equal weighting to the notion of sensitivity and specificity and may not be ideal for the assessment of screening thresholds for diabetes in clinical practice.
In 13 cases, a global EDE-Q score of 2.3 showed maximum validity coefficients when associated to the evaluation of objective bulimic episodes and exercise for the purpose of weight control (sensitivity = 0.83, specificity = 0.96, positive predictive value = 0.56).
Overall weight and sensitivity of the new design is compared with Alnico-V flow meters.
Health could be defined theoretically in terms of certain measured values; for example, a person having normal body temperature, pulse and breathing rates, blood pressure, height, weight, acuity of vision, sensitivity of hearing, and other normal measurable characteristics might be termed healthy.
