Design outcomes

Primary

Measure	Time frame
The target criteria are the Intraclass Correlation Coefficient (ICC) for comparing the agreement of the assessment of the test persons with different switching times. In addition, the detection rates of RAPD should be descriptively evaluated, taking into account the changeover times, as well as sensitivity and specificity.	—
