Poor repeatability
WebOne study observed that repeatability for the 6MWT and the ISWT was comparable, but that the ISWT was more reproducible. 18 However, another study showed that the ISWT was more repeatable than the 6MWT. 21 One study reported that both the 6MWT and the ICET were reproducible. 30 The ESWT was reported to be more repeatable than the ISWT in … WebRepeatability is expected to give the smallest possible variation in results. Intermediate precision ( s intermediate precision , s RW ) (occasionally called within-lab reproducibility ) is, differently from the repeatability, the precision obtained within a single laboratory over a longer period of time (generally at least several months) and takes into account more …
