Outcome measure | Reliability, measurement error and responsiveness | Criterion concurrent validity (gold standard) | Criterion predictive validity | Construct validity (hypothesis testing) |
---|---|---|---|---|
Functional capacity | Â | Â | Â | Â |
6-minute walk test | x | x | 8 studies [22–27, 39–41], predicts: survival, post-op outcomes (complications, LOS, 6MWT, HRQoL) and development of RP | |
12-minute walk test | x | x | x | x |
Incremental-shuttle walk test | x | 1 study [30], strongly correlated with CPET | 3 studies [30, 44, 64], moderately correlated with muscle strength; little, moderate and strong correlation with RFT; little correlation with mastery questionnaire | |
Endurance-shuttle walk test | x | x | x | x |
Stair-climb test | x | 1 study [29], strongly correlated with CPET | 13 studies [21, 22, 32–39, 41–43], predicts: post-op outcomes (complications, LOS, cost) and survival | 2 studies [20, 31], strong correlation between VO2peak and altitude reached; direct association between pre and post-op SCT results |
