Multivariate logistic regression with acceptance and uptake of the HPV vaccine as outcomes.

Model 1: including baseline characteristics; model 2: including barriers perceived at baseline; model 3: including baseline characteristics and barriers obtained by stepwise backward regression – model 4: model 3 + acceptance and being well-informed about the HPV vaccination program.
AOR: adjusted odds ratio – CI: confidence interval.
°average of: doubt the vaccine works, fear of side effects and interference with fertility, and afraid of unsafe administration; alpha  =  0.90.
°° average of: vaccination takes a lot of time and 3 doses are inconvenient; alpha  =  0.79.
nw: not withheld in backward stepwise regression.
* p<0.05, ** p<0.01, *** p<0.001.
