Estimated symptom and functional networks of each item of CA-PROM for cancer patients in three latent subgroups. The network structure was a Gaussian graphical model, which was a network of partial correlation coefficients. Nodes represent symptoms or functions. The outermost grey rings of nodeds represent the predictability of symptoms or functions. Edges represent pairwise dependencies between the symptoms or functions under controlling for all of other correlations of a given node. Blue line indicates a positive correlation. The thicker the lines are, the stronger the correlation
