State the NISS value for the accident.
The NISS (New Injury Severity Score) is the sum of the squares of the three most severe AIS scores, regardless of any body region.
NISS is a variation of ISS, intended to correlate better with the prediction of the death of the road user.
Its calculation is simpler than the ISS, since it does not distinguish between body regions.
