Ghali and colleagues found that the addition of two essential clinical predictor variables (extent of coronary disease and ejection fraction) to a multivariate analysis of administrative data produced an unbiased assessment of the effect of sex on revascularization. Although this demonstrates the inadequacy of some administrative data for ...References1. Ghali WA, Faris PD, Galbraith PD, Norris CM, Curtis MJ, Saunders LD, .
