^aPast week status assessed at annual assessments with the Beck Depression Inventory-1.

^bSite, age and pre-surgery smoking status, which were related to missing follow-up data, and surgical procedure were forced into the model. The model also controlled for pre-surgery factors reported in table 3 and the baseline SF-36 general health and Beck Depression Inventory-1 depressive symptoms scores.

^bNone of the comparisons of interest were significant.
