– Five yr absolute survival price refers to the share of individuals affected by the same illness, who’re alive 5 years after the illness is identified. That means, it doesn’t take into account the final inhabitants and depends on the share of the individuals with the illness.
– Five yr relative survival price refers to the share of individuals affected by the same illness alive 5 years after the illness is identified, divided by the share of the general inhabitants alive after 5 years. For occasion, if the 5-year relative survival price for a particular stage of most cancers is 90%, it signifies that sufferers who’ve most cancers are, on common, about 90% as doubtless as individuals who don’t have most cancers to dwell for not less than 5 years after being identified.
