Fig. 9: CAC score distribution across internal and external sites used for the non-gated model.
From: Automated coronary calcium scoring using deep learning with multicenter external validation

Violin plots show median (white point), each data point (horizontal lines), and interquartile range (vertical gray bar). Note that though the plots extension below a CAC score of 0 reflects properties of the kernel density estimator associated with violin plots. CAC score of less than 0 would not be realistic.
