Because surgical decision making is key to surgical outcome, surgeons are constantly searching for simple, reliable methods of risk assessment. Morris and colleagues use sophisticated statistical analysis to demonstrate statistically significant relationships between outcomes and IAF. However, one needs to know an individual's probability of an outcome for stratification and to make a decision that avoids poor outcome. The odds ratios (ORs) reported in the article by Morris et al do not directly provide probability.
