  1. Univariable logistic regression was performed first and the factors with P < 0.10 were included in the multivariable logistic regression. As a result, age, extraocular muscles operated, occurrence of oculocardiac reflex and use of penehyclidine were selected for multivariable logistic regression. CI Confidence interval, EOM Extraocular muscles
