When comparing the medians (interquartile ranges) of the 2 GA-T trials performed by the participants, no significant difference was noted, although the time to complete the second trial was shorter [365 (260-545) s vs 360 (250-540) s, P=0.81]; highly significant intraobserver agreement (P<0.0001) was observed between the measurements of the 2 GA-T trials (ICC=0.97 and 95%CI: 0.96-0.99).
