1 Optimal prediction of mortality after abdominal aortic aneurysm repair with statistical models 
Vassilis Georgiou Hadjianastassiou, MRCS, Leonardo Franco, PhD, Jose M. Jerez, PhD, Iordanis E. Evangelou, DPhil, David R. Goldhill, Paris P. Tekkis, Linda J. Hands  Journal of Vascular Surgery  Volume 43, Issue 3, Pages e3 (March 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Calibration chart for the predictive models as applied to the validation set of observations. Bars represent the observed and predicted in-hospital percent mortality risk.

3 Fig 2 Subgroup analysis by Chronic Health and operative urgency status for the predictive models (validation set). Error bars represent the 95% confidence interval of the in-hospital percent mortality risk.
