TLDR
The c statistic, or area under the receiver operating characteristic (ROC) curve, achieved popularity in diagnostic testing, in which the test characteristics of sensitivity and specificity are relevant to discriminating diseased versus nondiseased patients, may not be optimal in assessing models that predict future risk or stratify individuals into risk categories.
Abstract
I am pleased that Pepe et al agree that the C-statistic is not a relevant measure of clinical value despite its use as such in the clinical literature They remain, however, interested in sensitivity and specificity It is true that in the high-density lipoprotein example the sensitivity, or probability of inclusion in the highest risk group among cases, improves in the model with high-density lipoprotein, whereas the specificity, or probability of inclusion in the lowest risk group among controls, declines The model with high-density lipoprotein …

Evaluating the added predictive ability of a new marker: From area under the ROC curve to reclassification and beyond

TL;DR: Two new measures, one based on integrated sensitivity and specificity and the other on reclassification tables, are introduced that offer incremental information over the AUC and are proposed to be considered in addition to the A UC when assessing the performance of newer biomarkers.

Updating and Validating the Charlson Comorbidity Index and Score for Risk Adjustment in Hospital Discharge Abstracts Using Data From 6 Countries

TL;DR: The updated Charlson index of 12 comorbidities showed good-to-excellent discrimination in predicting in-hospital mortality in data from 6 countries and may be more appropriate for use with more recent administrative data.

Assessing the performance of prediction models: a framework for traditional and novel measures.

TL;DR: It is suggested that reporting discrimination and calibration will always be important for a prediction model and decision-analytic measures should be reported if the predictive model is to be used for clinical decisions.

Extensions of net reclassification improvement calculations to measure usefulness of new biomarkers

TL;DR: Net reclassification improvement offers a simple intuitive way of quantifying improvement offered by new markers and has been gaining popularity among researchers, however, several aspects of the NRI have not been studied in sufficient detail.

The meaning and use of the area under a receiver operating characteristic (ROC) curve.

James A. Hanley, +1 more
- 01 Apr 1982 - 
TL;DR: A representation and interpretation of the area under a receiver operating characteristic (ROC) curve obtained by the "rating" method, or by mathematical predictions based on patient characteristics, is presented and it is shown that in such a setting the area represents the probability that a randomly chosen diseased subject is (correctly) rated or ranked with greater suspicion than a random chosen non-diseased subject.

TL;DR: A simple coronary disease prediction algorithm was developed using categorical variables, which allows physicians to predict multivariate CHD risk in patients without overt CHD.

A comparison of goodness-of-fit tests for the logistic regression model.

TL;DR: An examination of the performance of the tests when the correct model has a quadratic term but a model containing only the linear term has been fit shows that the Pearson chi-square, the unweighted sum-of-squares, the Hosmer-Lemeshow decile of risk, the smoothed residual sum- of-Squares and Stukel's score test, have power exceeding 50 per cent to detect moderate departures from linearity.

Limitations of the Odds Ratio in Gauging the Performance of a Diagnostic, Prognostic, or Screening Marker

TL;DR: An illustration of the relation between odds ratios and receiver operating characteristic curves shows, for example, that a marker with an odds ratio of as high as 3 is in fact a very poor classification tool.
