E-045 Nihss and its component subscores are suboptimal predictors with colinearity

Conclusions NIHSS composite score is a suboptimal predictor for assessed patient outcomes. Principal component analysis improves predictive value of assessment with a statistically significant effect for pre-intervention patient outcomes analysis. Statistically significant variables are heavily dependent of NIHSS subscores, and variation in the distribution of these subscore may represent a significant source of bias. References .
