SSV model is a useful research tool
In their paper (see pp 401),1 Counsell et al compare a “six simple variable” (SSV) model, which they developed for predicting outcome after stroke,2 with two other simple models and with clinical predictions of stroke outcome, and find that their model is at least as good as the other evaluated predictive systems.
Predictive models of stroke outcome may be useful in epidemiological studies and clinical trials of stroke to stratify cohorts by baseline severity, and they could also guide patient management. A multitude of predictive models already exists,3 and one might argue that yet another model …
