Life Expectancy in Pleural and Peritoneal Mesothelioma

Table 2

Comparison of empirical (Kaplan-Meier) and modeled (Cox) survival percentages. Sample sizes () refer to the Kaplan-Meier cohorts. The sample sizes for these two Cox models were = 10,258 cases for pleural (79% staged) and = 1,229 cases for peritoneal (56% staged). Note: the two Cox models used for this table contained terms only for age, sex, and localized/regional/distant/missing.
