CI: confidence interval; NK: not known; CI5: Cancer Incidence in Five Continents; NCI-SEER: National Cancer Institute’s Surveillance, Epidemiology, and End Results Program: nine registries.
^aAll rates are age adjusted to Segi’s world standard population [9]; African rates are shown only for populations at least 95% black or are specific for black Africans.
^b95% CIs were obtained directly from CI5, were estimated for data from the Cancer in Africa publication by multiplying the standard error (incidence rate divided by the square root of the total number of cases) by 1.96, and adding to and subtracting from the incidence rate to obtain the upper and lower bounds, respectively, or were provided by SEER*Stat.
