NCT ID NCT04131933
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether giving doctors a free online risk score (PREDICT 2.1) changes how often they order an expensive genetic test called Oncotype DX for early-stage breast cancer. Over 600 patients took part. The goal was to see if the algorithm could help doctors make better decisions about who really needs the costly test.
