The EQ-5D is a useful preference-based measurement of HRQOL that incorporates values or utilities for health status and can be used in health-economic analyses to optimize resource allocation [ 34, 35].
On this basis, it is possible that we excluded articles that may contain useful preference information because they used definitions that did not meet our inclusion criteria.
We are not aware of any existing IBD instrument/tool that captures the important outcome of patient preference, and as such, the IBD PRTI may have a future role as a useful indicator of patient preference.
This is a useful indication of duck preferences for water depth, but not a definitive measure because observations of bathing behaviour suggested that pools of different depths were used in different ways (30 cm pools were more suitable for swimming, but more dabbling was performed in the 10 cm pools than in deeper pools) and because not all groups of ducks made the same choices.
Despite the lack of evidence supporting an immunocompetence account of facial masculinity, it is quite possible that this could prove to be a useful explanation of observed preferences for other sexually dimorphic traits in humans, such as voice pitch, color cues, and body size.
And it, too, serves as a useful caution against the natural preference for tidy stories with well-defined heroes.
The ASUI represents a useful and valid measure of preference-weighted asthma symptoms for use in clinical trials and clinical management.
The nutritional geometrical model is a useful representation to describe feeding preferences and the response of the flies to imbalanced diets [ 14, 15]. Figure 2 uses this representation to compare nutrient intakes by normoxic and hypoxic flies.
Recognizing your own preferences is a useful tool in self-development.
If the hypothesis of an automatic process is confirmed, our experimental design could be a useful tool to detect sexual orientation or sexual preferences independently from social desirability.
The Youden index is a useful metric when there is no preference between sensitivity and specificity.
