Comparison of observed discordances to analytical variation.

<p>Each line represents the difference between the Jaffe result and enzymatic result. The vertical lines indicate the decision limit and two standard deviations of the difference (Jaffe-enzymatic) due to measurement imprecision at the decision limit. The arrows are directed from the enzymatic result toward the Jaffe result (the Jaffe result is greater than enzymatic when arrows point from left to right). Heavy lines indicate statistically significant discordances (i.e., greater than two standard deviations of the analytical variation) and light lines indicate nonsignificant discordances.
