Distribution of demographic attributes including age, gender, race or ethnicity, and obesity prevalence among patients from each of the eight participating health systems in the PEDSnet network

The eight hospitals are indexed from A to H. The height of the bars indicates the prevalence of each demographic variable within each hospital. The outermost circle corresponds to a prevalence of 0.6, with inner circles indicating lower prevalence levels in increments of 0.2. This visualization reveals variations in ethnicity and obesity metrics across different health systems, highlighting the heterogeneity of patient demographics between hospitals.
