Comparison between the actual wear level (determined based on radiography followups) and the predicted wear level (from LDA technique)

Actual wear level	Estimated wear level			% correctly classified
	Low	Moderate	High
Low	20	2	3	80%
Moderate	1	25	3	86%
High	2	2	15	79%

Twenty of 25 patients with low wear rate were correctly classified as “low-wear”; 25 of 29 with moderate wear rate were correctly classified as “moderate wear”; 15 of 19 with high wear rate were correctly classified as high wear.
