Fig. 4From: Cerebrospinal fluid cell count variability is a major confounding factor in external ventricular drain-associated infection surveillance diagnostics: a prospective observational studyCorrelations of paired samples. Scatter plots comparing sample 1 on the x-axis with sample 2 on the y-axis for each CSF parameter. The \(R^2\) of linear regression is given. The correlations are seen weaker for cells exhibiting a greater variability of paired samplesBack to article page
