Physiotherapists Have Accurate Expectations of Their Patients’ Future Health-Related Quality of Life after First Assessment in a Subacute Rehabilitation Setting

Table 3

Intraclass-correlation coefficient (ICC), mean EQ-5D-3L utility and Visual Analogue Scale (VAS), and limits of agreement (LOA) between physiotherapist predicted and actual discharge health-related quality of life reports (𝑛=232).

^∗𝑃 value < 0.05 indicated that a systematic difference exists (i.e., predicted discharge health-related quality of life was consistently higher or lower than the actual self-report at discharge).
