3.2. Effectiveness evaluation
SECONDARY
The evaluation of effectiveness of this experiment included primary and secondary effectiveness indicators. The primary effective indicator was the consistency of the test instrument and the control instrument in measuring the completion of the task, which was evaluated by the Bland–Altman plot. In addition, the completion rates of the vital sign measurement and the success rate of the first measurement were also used as the main effectiveness measures. Secondary indicators included vital signs measurement results, the error rate of use, and subjective satisfaction.
