PPR is the panel passing rate for the number of subjects tested.

Criterion 1: Achieve FFo ≥ 500 on at least one of the two donnings.

Criterion 2: Achieve FFo ≥ 500 on the first donning only; the second donning was not evaluated for this analysis.

§

Criterion 3: Achieve a FFo ≥ 500 for both of the two donnings.
