Values of p in bold are significant (pGoodness of fit (Hosmer-Lemeshow) chi-square p value = 0.27.Area under the ROC curve estimated by the c statistic = 0.31.The following variables were entered into the model: age, pre-existing co-morbidity, epileptic seizure, status epilepticus, GCS score at ICU admission, headache, acute hypertension, mean arterial pressure on scene, highest glycaemia value, grey matter involvement, brainstem involvement, ganglia involvement, total number of brain areas involved, haemorrhagic complication at first imaging, time from PRES onset to causative-factor control (hours), SAPS II score, duration of mechanical ventilation, mechanical ventilation, refractory status epilepticus, length of ICU stay, length of hospital stay, toxaemia of pregnancy, and exposure to toxic agent.95%CI, 95% confidence interval; PRES, posterior reversible encephalopathy syndrome.
