The upper section of the table displays the expected numbers of EAC cases without aspirin, the 1st row is by 5 year period interval and the 2nd row is a cumulative tally.
The lower section displays the prevented numbers of cancers for each 5 year period as absolute numbers (1st row) and percentages (2nd row)) and the 3rd row is a cumulative tally of cancers prevented by aspirin. The values in parentheses represent the range found using the superior (top 1%) parameter sets.
