他們處理數據的時候用了 total number of newly diagnosed cancer patients

他們是這麽計算的：

The total number of newly diagnosed cancer patients for 22 major adult
malignancies was determined from cancer registry data in Australia and from the Surveillance Epidemiology and End Results data in the
USA for 1998. For each malignancy, the absolute number to bene?t was the product of (a) the total number of persons with that
malignancy; (b) the proportion or subgroup(s) of that malignancy showing a bene?t; and (c) the percentage increase in 5-year survival due
solely to cytotoxic chemotherapy. The overall contribution was the sum total of the absolute numbers showing a 5-year survival bene?t
expressed as a percentage of the total number for the 22 malignancies

雖然他們用了隨機臨床測試的結果，但他們的對比組並不真正是臨床測試裏的對比組。
