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).
