1
Subjects may have been on more than one serotype and the total of the n's are greater than the total number of subjects
2
Percentages are based on the number of people who responded to have previous botulinum toxin therapy
3
Percentages are based on non-missing values
4
The “n” and percentage is based on the number of individuals who responded “yes” or “no” indicating employment. Those who indicated that they are not employed or those with missing data were excluded from the percentage calculation
Abbreviations: N/n, total subject population/subset of total subject population; %, percentage; SD, standard deviation
