Probability assessment of intracerebral hemorrhage in prehospital emergency patients

Table 2 Single items of the NIHSS in patients with ICH, AIS, TIA and SM (Derivation cohort). The sum score and all items of the NIHSS for the ICH and AIS, TIA, SM patients separately as well as the difference between ICH and AIS/TIA/SM patients are shown. The sum score is depicted as the mean average score for all patients, the units for the single items are shown in points. The items depicted in bold are part of the “short NIHSS” and the ph-ICH score. A pdf version of the NIHSS with an explanation for all items of the score can be found here: https://www.stroke.nih.gov/documents/NIH_Stroke_Scale_508C.pdf
