Table 1 Main characteristics of Clinical-Genetic Research, Treatment, and Public Health Registries according to the most informative variables emerged after the random forest method. Variables reported in the table characterize most of the registries of each class.
From: Characterization and classification of Rare Disease Registries by using exploratory data analyses
