On the C-statistics for Evaluating Overall Adequacy of Risk Prediction Procedures with Censored Survival Data (2011, neutral): “Note that Gönen and Heller [17] proposed a method for censored survival data to estimate pr(T2>T1|g(Z1)>g(Z2)), which is also a concordance measure and has a similar form to (1), but we do not focus on this type of measures in this paper.”
Assessing the performance of prediction models: a framework for some traditional and novel measures (2010, methodology): “Gonen and Heller have proposed a method to estimate a variant of the c statistic that is independent of censoring, but holds only in the context of a Cox proportional hazards model.(7) Furthermore, time-dependent c statistics have been proposed.”
Prognostic Models With Competing Risks: Methods and Application to Coronary Risk Prediction (2009, background): “First, by conditioning on the events being observed, the c index depends on the censoring distribution.(33) This is a minor issue in our case study, in which all patients have a similar follow-up duration and loss to follow-up is minimal.”
External validation of a Cox prognostic model: principles and methods (2013, methodology): “Here, for the purpose of illustration we focus on three measures: Harrell’s c-index of concordance [34], Gönen andHeller’s unbiased concordance statisticK [35], and the Royston-Sauerbrei D statistic [26].”
Toward more realistic drug–target interaction predictions (2014, positive): “concordance index (CI) as an evaluation metric for the prediction accuracy [32].”
A novel clinical risk prediction model for sudden cardiac death in hypertrophic cardiomyopathy (HCM risk-SCD). (2014, methodology): “Comparison with conventional risk factors Clinical practice guidelines consider severe hypertrophy (maximal wall thickness ≥30 mm), non-sustained ventricular tachycardia (NSVT), family history of SCD, and unexplained syncope as conventional risk factors of SCD.1,2 To compare the risk model developed”
