and RT-interval₅ or RT-point₅. The Bland-Altman analysis indicates that the limits of agreement between (A) Real-time interval observation over 5 minutes (RT-interval₅) with a bias (underestimation) by real-time scores of −0.11 and limits of agreement ranging from −0.65 to 0.44. (B) Real-time point observation over 5 minutes (RT-point₅) with a bias (underestimation) by real-time scores of −0.08 and limits of agreement ranging from −0.63 to 0.50.
