Computed Ranks are competition ranks (ties share a rank). Percentile = share of eligible entities ranked at or below this one in the ranking direction.

"Deadliest" is ambiguous: annual deaths, age-standardized mortality rate, mortality-to-incidence ratio and 5-year survival rank cancers differently. CancerIndex publishes each as a separate metric.
