Discrimination between baseline and severe neutropenia. The median numbers of majority events observed per minute, when averaging across all available capillaries per patient, allow discriminating between baseline (blue dots) and severe neutropenia (red dots) for the 22 video datasets and 11 patients of our study. The corresponding cross-capillary variability is also shown for each patient (blue and red bars with notch extremes determined as q 2 ± 1.57(q3 − q1)/N1/2, where the q i are the respective quartiles, and where N = 11 is the amount of paired data points). The optimal threshold to separate baseline from severe neutropenia was seven events per capillary minute (dotted black line). The X-axis is labeled with the patient IDs together with their amount of analyzed capillaries in brackets. The median amount of capillaries used per patient was four. The difference in patient counts between baseline and severe neutropenia was statistically significant.
