We read with great interest the recent article in this journal by Dreisbach et al.
in which they analyzed and clustered unrelieved symptoms in patients with one or more
chronic conditions.
In particular, Fig. 1, Panel A, which illustrates the overlap of chronic conditions, caught our eye. We
would like to use this as an opportunity to point out a novel and innovative approach
to visualize intersecting sets which we find particularly useful for illustrating
multimorbidity in chronically ill populations.
