A high risk rating was defined as either the CNN or teledermatologist rated a photo as high risk. Low risk was defined as neither the CNN nor the teledermatologist rated a photo as high risk. Percentages are number of people with a claim per subcategory of claims. P-values are the difference in proportion of claims, calculated using a two proportions z-test or corresponding odds ratio’s using Fisher’s Exact Test for Count Data.
