a

Likert scale response values were reverse coded where necessary such that lower scores correspond to a negative review and higher scores correspond to a positive review

b

Significant difference (p <0.05) in means for the enema and applicator

c

Significant difference (p <0.05) in means for the enema and suppository

d

Significant difference (p <0.05) in means for the applicator and suppository

e

Among those who had intercourse (anal and/or vaginal) in the past 2 weeks/since their last telephone interview

f

Not correlated with either of the identified factors
