It is also important to recognize that r/K selection theory proposes not a qualitative categorization of evolutionary outcomes but instead proposes a continuous gradient of relative contributions of r-selected and K-selected traits for any given species.
Data abstracted from each work were entered into an Excel database; categorization of all outcomes into priority themes and questions was repeated for verification.
For instance, biomarkers in the form of single molecular components or qualitative component lists will probably be inadequate even for categorization of treatment outcomes.
Our categorization of the outcome variable may also be a limitation.
The first logistic regression equation adopted HADs Anxiety as the criterion variable for categorization of the outcome trajectories, whereas the second used HADS Depression.
Others have used logistic regression after categorization of the outcome [ 4, 12, 14], which could lead to arbitrary choice of categories such that results could be sensitive to choice of cutoff values.
These past studies were limited by inadequate adjustments [ 59], loss of data quality due to the heterogeneity of the population (not specific to T2D), categorization of continuous outcome data and data-driven analysis [ 60, 61].
The framework of the ROC based signal detection analysis utilized in this paper provides a non-biased and completely data driven method to identify regions and cut-points for categorization of treatment outcome.
From among these respondents, three percent (n = 1735) were excluded from the analysis because they failed to respond to one or more of the items concerning alcohol use, which was necessary for categorization of the outcome variables.
Analysis of BCR-ABL in the progenitor cell compartments permitted a further categorization of post-relapse outcome.
