Fig. 5From: A differential of the left eye and right eye neurological pupil index is associated with discharge modified Rankin scores in neurologically injured patientsFor each patient in the < low NPi high diff > group, time of the first occurrence of an NPi differential is included in a histogram relative to the first time of occurrence of an abnormal NPi (set at zero). The peak of the distribution at time zero reveals a marked synchronicity between the two types of abnormalities and, its skewness towards the negative axis, a leading effect of the NPi differentialBack to article page
