OR, odds ratio; CI, confidence interval. N=55 (34 received surgical management and 19 received medical management).

1

Multivariate analysis included Monthly income, Social support q15 (Question 15: ‘when you may need help … do you turn to the people available to you?’) and Depressed in a combined model.

2

Monthly income was measured in brackets of $400 per month, with a base bracket of $0.

3

Social support was measured on a 5-point Likert scale (1:Never, 2:Rarely, 3:Sometimes, 4:Usually, 5:Always) and was found to be linearly related to the probability of surgical treatment.

4

When Education was included in a separate regression in place of Income (due to collinearity), the Education adjusted OR was 2.82 (0.69, 11.45), p=.148.
