Note:—IQR indicates interquartile range.
When comparing the performance of multivariable logistic regression models in predicting good outcome at 90 days in patients with near-complete recanalization, model performance slightly increased and information loss decreased when CTP lesion volumes were added in addition to baseline variables, though the area under the curve confidence intervals overlapped (Table 4). Data in columns 2 and 3 are medians and interquartile ranges.
