For statistical analysis, OS and DFS were defined, respectively, as the interval between radical surgery and death or last follow-up visit and as the interval between radical surgery and clinical progression or death or last follow-up visit if not progressed.
For statistical analysis, OS and PFS were defined, respectively, as the interval between the start of chemotherapy to death or last follow-up visit, and as the interval between the start of chemotherapy to clinical progression or death, or last follow-up visit if not progressed.
For statistical analysis, overall survival (OS) and progression-free survival (PFS) were defined, respectively, as the interval between the start of cetuximab and irinotecan therapy to death or last follow-up visit and as the interval between the start of cetuximab and irinotecan therapy to clinical progression or death or last follow-up visit if not progressed.
For statistical analysis, overall survival (OS) and disease-free survival (DFS) were defined, respectively, as the interval between surgery to death or last follow-up visit and as the interval between surgery to clinical progression or death or last follow-up visit if not progressed.
For statistical analysis overall survival (OS) and time to progression (TTP) were defined respectively as the interval between the start of cetuximab and irinotecan therapy to death or last follow-up visit and as the interval between the start of cetuximab and irinotecan therapy to clinical progression or death or last follow up visit if not progressed.
Progression-free survival was calculated from entry in the study to progression or death from disease (or end of follow-up if not progressed).
After everything that has happened, this display – like the 2-0 defeat of Aston Villa – could represent if not progress then at least a bottoming-out, or clinging onto the last few rungs of a ladder that the team had been sliding down all season.
As science does move on (if not progress), explanations presented by narrators, historical personages, or today's scientists in works of evolution by example will inevitably be modified, displaced, or even discarded in light of new discoveries and conceptual changes in science.
This will also allow you to act if they are not progressing.
Keeping action plans on schedule if things are not progressing as desired.
