Short description: 

This thesis examines methods for updating searches for systematic reviews of healthcare interventions on the base of 77 systematic reviews. The Related Article search showed the highest recall. Relative performance of the test searches was consistent regardless of whether the intervention was a drug, device or procedure.

The pairing of Related Article RCT and Clinical Query gave excellent recall of new relevant material.
