SCENTinel 1.1 accuracy matrix: potential response patterns that determine overall score classification of correct/incorrect.

Response Pattern #	Odor Detection	Odor Intensity (range 1–100)	Odor Identification		Overall Score
			First attempt	Second attempt
1	Correct	≥ 21	Correct	NA	Correct
2	Correct	≤ 20	Correct	NA	Incorrect
3	Correct	≥ 21	Incorrect	Correct	Correct
4	Correct	≤ 20	Incorrect	Correct	Incorrect
5	Correct	≥ 21	Incorrect	Incorrect	Correct
6	Correct	≤ 20	Incorrect	Incorrect	Incorrect
7	Incorrect	≥ 21	Correct	NA	Correct
8	Incorrect	≤ 20	Correct	NA	Incorrect
9	Incorrect	≥ 21	Incorrect	Correct	Incorrect
10	Incorrect	≤ 20	Incorrect	Correct	Incorrect
11	Incorrect	≥ 21	Incorrect	Incorrect	Incorrect
12	Incorrect	≤ 20	Incorrect	Incorrect	Incorrect

Note: # = response pattern number. Odor detection is by a triangle test. “First attempt” is a four-alternative forced-choice. “Second attempt” is a three-alternative forced choice.
