‡ Lower probability of receiving rehabilitation services; ☥ higher probability of receiving rehabilitation services; Note. Estimate = regression coefficient; S.E. = standard error; p = p-value; OR = odds ratio; CI 2.5% = lower bound of the 95% confidence interval; CI 97.5% = upper bound of the 95% confidence interval; bold p-values are significant at 5% α-level; GCS = Glasgow Coma Scale; Brain Injury AIS = Abbreviated Injury Scale, Brain Injury severity; ISS = total Injury Severity Score; ER = emergency room; ward = admission at hospital ward; ICU = intensive care unit.
