Statistical Analysis
neurologic deficits
REGRESSION
Clinical characteristics of patients according to availability of the NIHSS and EQ-5D at 90 days were compared using descriptive statistics. We assessed the association between neurologic deficits (NIHSS sum score and individual NIHSS item scores) and each EQ-5D dimension score with univariable ordinal logistic regression. For the EQ-5D utility score, censoring from above takes place, which means cases with a value at or above some threshold (i.e., utility of 1), all take on the value of that threshold, so that true value might be equal to the threshold, but it might also be higher.Missing data were imputed by multiple imputation by chained equations based on relevant covariates including outcomes.
