A small selection of causes have continued to do wristbands, including armed forces charity Help for Heroes, for which the bands have been a fundraising tool since it launched in 2007 (a spokesperson indicated the bands were still popular).
It certainly seems superior to recent research in which some US undergraduates were presented with a selection of celebrities and social causes, as a detailed questionnaire sought to determine which star would be the most effective advocate for a cause, in terms of their fit with the mission and their ability to make people part with money.
Rather, mutations or chromosome damage would be necessary to induce leukaemia, but a proliferative stimulus (infection) causing a selection of the mutated clones would also intervene.
Although even low concentrations of antimicrobials are sufficient to cause a selection of resistant bacteria [ 30], the extent of compositional changes in the calves' intestinal microbiota may be different if TWM, WWM or both is fed to calves.
The difference in the response rate between the two surveys could have introduced bias, causing a selection of those most interested in the topic, i.e., the surgeons with the highest case load [ 13].
Respondents were also asked about their recall of media stories about depression and their current health status, as well as their views on which of a selection of options was the likely cause of the problem in the vignette, what might be helpful for treating the problem and their view on the likely prognosis for the person depicted in the vignette.
This could be explained by the study design, which required that participating patients had to travel to the lung function laboratory of the University Medical Hospital Heidelberg, which might have unintentionally caused a selection of patients with a higher probability and/or severity of disease.
As shown by the variation between studies in selection of causes of death deemed to be amenable to health care intervention [ 15] this selection is to some extent arbitrary.
It is interesting to find out in future research in other countries but in the same selection of causes of death, whether different or similar trends can be observed.
Furthermore, the selection of causes of death that are "amenable to health care" is time-dependent: technological progress constantly increases the opportunities to prevent premature deaths through secondary prevention and treatments.
