Testing for Mechanistic Interactions in Long-Term Follow-Up Studies

In follow-up studies, interactions are often assessed by including a cross-product term in a (multiplicative) Cox model. However, epidemiologists/clinicians often misinterpret a significant multiplicative interaction as a genuine mechanistic interaction. Though indices specific to mechanistic interactions have been proposed, including the 'relative excess risk due to interaction' (RERI) and the...

Trabeculectomy: long-term follow-up.

The postoperative course of 309 eyes subjected to trabeculectomy has been studied over a 7-year period.
