Fig. 3.
Average index of impairment over seven tests. For each test, the index compared a strain to the most impaired strain on that test, where the most impaired strain received a score of 100%. Strain PL/J was markedly higher than any other strain, but it is evident from Fig. 2 that no strain was consistently high or low in impairment across all tests. Ranks for almost every strain were widely dispersed.
