Smell test
Sense of smell (UPSIT) improved significantly in all but one (92%) of the patients treated with benralizumab (SD=6.2; P=0.013). The change in mean UPSIT score at week 20 compared to baseline was 6.6 points, increasing from 12.2 to 18.8 answers correct out of a maximum of 40. Eight of twelve placebo patients also showed modest improvement in UPSIT scores but this did not reach statistical significance (SD=6.8; P=0.139).
