Fig. 3From: Cerebrospinal fluid cell count variability is a major confounding factor in external ventricular drain-associated infection surveillance diagnostics: a prospective observational studyVariability of paired samples. Density plots of the pair-wise \(\Delta\) distributions for R-samples (light gray) and C-samples (dark gray) for all CSF parameters, respectively. The x-axis shows the pair-wise differences or \(\Delta\). The area under each will be sum-able to 1, defining the y-axis values. One R-sample with a \(\Delta\) of − 3505 was excluded from the granulocyte plot in order to improve visualization. R-samples: paired samples around a patient repositioning. C-samples: paired non-repositioned samplesBack to article page
