For each bait, a selected limited set of interacting preys is classified in categories of distinct heuristic values.
While the DHSs offer the unique advantage of performing cross-country analyses of data collected using a standardized questionnaire and methodology, when interpreting these results one needs to consider that surveys included in this analysis were conducted over an 8-year period (1998 2006) and represent populations in a select and limited number of developing countries.
However, any typology is bound to be arbitrary to some extent, as there is a need to select a limited number of attributes from a universe of possible choices [ 20, 29].
Given the large uncertainty of such a estimate, to select a limited number of unrelated highly significant variables, we applied a stepwise regression approach and repeated the analyses controlling only for this parsimonious set of variables (model 2).
Biomarker identification is a process to select a limited number of biomolecules that convey the essential biological information distinguishing a disease state from a nondisease state.
The group could not agree on a simple method of selecting a limited set from such a broad and diverse class of materials; even within one class there is currently no way to determine which material is the most representative.
In addition, we observed evidence for effect modification, but even within this large multicentre study, the power to reliably detect effect modification is limited and therefore we selected a limited set of interactions to evaluate a priori.
The exploratory nature of the study led us to use a small sample and select a limited number of convenience sites.
The main limitation in this model reduction approach is the selection of the metabolites, since selecting a limited set of metabolites from a ranked list is usually arbitrary.
Several exclusion criteria, including absence of patients with kidney dysfunction or taking drugs known to affect serum urate (such as aspirin or diuretics), made this a selected population with limited generalizability.
