The Ratio Fallacy, with Special Reference to the Cardiac Index.

Abstract

When comparing cardiac outputs in children of different sizes, or deciding on the normality of these outputs, we often convert the absolute output to the output per m2 body surface area-the cardiac index. For small infants, this leads to potentially large errors. The best way to evaluate these outputs is to determine their z values.
