The optimization technique iteratively explores the search space of TC subsets, looking for a solution with highest coverage of the given test adequacy criterion [22, 23].
These techniques explore the space of possible solutions (subsets of TCs), seeking the solution (reduced TS) that best attends the given test adequacy criterion.
Search-based optimization strategies arise as a promising way to treat this problem, as they explore the space of possible solutions (subsets of TCs), seeking the solution that best satisfies the given test adequacy criterion.
Therefore, different strategies have been used to demonstrate the relativity of such negative impact, based mainly on the verification of two key components: a) whether there is enough available evidence to support conclusions about the effectiveness of a given drug/intervention (adequacy of evidence), and b) whether that evidence implies about effectiveness (magnitude of benefit) [38, 39].
I take as given the adequacy of the evidence base assembled by the World Health Organization Commission on Social Determinants of Health (2008) and other authors (Yong Kim et al. 2000; Birn et al. 2009; Labonté and Schrecker 2011).
Given the adequacy of the metric properties of the Stoma-QOL suggested by the psychometric analyses, this study confirms the suitability of the instrument in clinical practice and in clinical research.
This may reflect a predominance of RCTs designed using drug-research methodology paradigms without due consideration given to adequacy of the technique used in delivering LLLT, leading to under dosing and negative outcome bias [ 65].
Another shortcoming in evaluating household food resources is the lack of consideration for the amounts of food and beverages present in the home, given the adequacy of food resources may relate to household size and composition [ 20, 65, 68, 69].
Given the adequacy of the metric properties of the Stoma-QOL suggested by the Rasch results as well as by the classical analysis, this study has shown the suitability of the instrument both for clinical practice and for clinical research.
Three of the COMRADE items focus on patients' ease of understanding information, patients' satisfaction with the information given, and adequacy of information about issues important for the decision, respectively.
