*Variables which are candidate for multiple linear regression (<0.05) were included in the model. Note: R² = 0.592, F (21,217) =14.985, p < 0.001.
Statistical significant (p < 0.05).
Married, illiterate, farmer, yes (for substance use, preoperative information, and knowledge of type of anesthesia), morning, absence of pain and minor were used as reference category.
