Alternatives: "a valuable representation of" or "an insightful indication of".
However, in this case I think the range of comments is a useful reflection of the responses of readers and are likely to be helpful in revision.
A good external validity in a sense of an adequate reflection of reality (is it correct?) does not necessarily mean a good (external) utility in a sense of a useful reflection of reality (what is it good for?
This might be a trivial result given the absence of monocytes, but can be argued that it is a useful reflection of the in vivo defect and how its magnitude compares with established molecular causes of mycobacterial susceptibility, such as IFNγ receptor mutations (Fischer, 2007).
Third, the current study is a useful proxy reflection of the people's perceptions of end of life care and is likely to relate to the deceased's experience.
Moreover, activated charcoal decolorized the 7H9 medium (see Fig. S1a in the supplemental material), suggesting that it bound small molecule components, and the charcoal quenched the fluorescence of resazurin (see Fig. S1b in the supplemental material), whose reduction to resorufin is a useful quantitative reflection of relative mycobacterial numbers (30, 31).
And there is no question that National Geographic's strong promotion of this scholarly achievement, at an April 6 news conference, in an April 9 television documentary and in two books, has stirred some useful reflection about the evolution of early Christianity and the paradoxes of Jesus' willing death on the cross, as well as about one aspect of Christianity's anti-Jewish imagery.
The value t d depends on many factors, including shape changes between the two pulses, errors in the LDV outputs due to the weak useful reflection and the existence of on-chip spurious reflections, and limitations in the algorithms used for retrieving Δ t.
The extensive cytokine connections between cells of and not of the immune system, at least as it is classically defined, should provoke useful reflection on the possible limits of conceptualizing the immune system narrowly and in isolation from other physiological systems.
By contrast, BNP might be more useful as a reflection of haemodynamic parameters, magnitude of symptoms, and systolic/diastolic function.
A more fundamental question is whether the PAS response is simply a useful curiosity, or a reflection of a previously unappreciated aspect of the phage life-cycles, the ability to successfully adapt to a "sub-optimal" environment for bacterial growth.
Our results further suggested that CD127 expression on CD8+ T-cells may be a useful indicator of current HIV disease status, as this marker was a reflection of current immunological status.
