Kwei KT, et al. - In univariate and multivariate analyses comparing code-to-imaging time (CIT) between mild and severe strokes, the researchers tested relationships between National Institutes of Health Stroke Scale scores (NIHSS), continuously and at different cutoffs, and CIT using spline regression, t tests for univariate analysis, and multivariable linear regression adjusting for age, sex, and race/ethnicity, presuming that perception of stroke severity would affect how quickly stroke code responders act. They reported that stroke scale scores <4 were correlated with longer response times. Findings revealed that milder strokes were linked with a longer CIT with a threshold effect at an NIHSS of 4.
