Metabolomics is primarily a data-driven, hypothesis generating science; however, so far most published research has been proof of principle, relying on complex statistical models as the endpoint of a given study.
The primary endpoint of a correlative study (SHIP36B) is the biopsy results at 36 months following treatment to examine the relationship between results and eventual recurrence after completion of radiotherapy.
Accordingly, before undertaking such research and in determining whether an IND is required before the study may lawfully commence, investigators and researchers as well as IRBs should take into consideration the "intended use" and, in particular, the intended focus and endpoint of a given study protocol.
Qualify of life (QOL) and cost analyses would be important secondary endpoints of such a study.
In our analysis, no single immune parameter correlated with the delay of the onset of PSA progression (an endpoint of the study); however, an artificial intelligence analysis uncovered tenuous trends in integrated outcomes of multiple parameters that might drive immunity into a particular direction (e.g., towards TH1-type response [10]).
For the primary endpoint of the study, a two-sided 95% confidence interval (CI) for the group difference 'test treatment minus reference treatment' was calculated for the percentage change from baseline in the JKOM score as non-inferiority analysis.
Thus, an early endpoint of this study was a comparison of the efficacy of 12 weekly injections of efalizumab with and without concomitant administration of topical corticosteroid ointment added during the third month of the treatment period.
Detection of EPE was at most a secondary endpoint of a number of studies, and many investigations analyzed low- and high-risk groups separately.
With incidence, the endpoint of our study, when a subject develops a cancer, this can be considered in relation to the oral anti-hyperglycemic agent used to that point and need not be confused by changes in medication subsequent to the diagnosis.
