The most significant factors associated with neurological deterioration, according to Table 4, were selected for further analysis in this model. Odds ratios for each group of baseline NIHSS reflect the odds of being admitted within that range of NIHSS scores in comparison to being admitted within the range of the other baseline NIHSS score groups. Additional combinations of risk factors (more than 3 at a time) could not be achieved due to sample size.
