a
Onabotulinum toxin A injections with a maximum effect.
b
The effect size, as measured by η2 value, is interpreted as small, approximately 0.02; medium, approximately 0.13; and large, approximately 0.26.
c
Adjusted for age at start of onabotulinum toxin A injections, sex, and race.
d
Additionally adjusted for number of injections and injection interval.
e
Further adjusted for smoking, current alcohol use, and employment status.
