Authors' conclusion
Extended A2-ultrasound examination identified more patients with LV involvement than the limited ultrasound method.
Study context
- Population
- Patients with newly diagnosed GCA, included at diagnosis

- Follow-up
- At diagnosis
Methodological detailspaired comparison: all patients examined by both methods
- Paired comparison: all patients examined by both methods
