Modified correlation networks for circulating dipeptidyl peptidase 3 (cDPP3) and day-two SOFA scores visualised using the corrr (https://corrr.tidymodels.org) package in R. The product of the Kendall τ and 1−p were visualised so that highly correlated points with low p-values are close. The proximity of the points is based on multidimensional clustering. The association is also shown by the colour intensity of the vertices (so that unconnected points have negligible association).
