The Bayesian clustering of individuals (Fig. 5) might at first seem to contradict a common source of recolonization of all populations, given that ELW from RIN, NIS and GUD formed one cluster, whereas the two populations from the Limfjord, KIL and FLY, formed a separate cluster.
High levels of PCE have been extracted from conventionally dry-cleaned fabrics, making such fabrics a common source of exposure to the general population (Sherlach et al. 2011).
As such, low dose exposure as it is the case in dental x-rays, is a common source of radiation in the general population.
The most common source of infection in the whole population was the respiratory, and the factors associated with progression to septic shock were catheter-related infection, age, female sex, temperature, and chronic lung disease.
Because of the natural distribution, drinking water is the most common source of arsenic exposure for the general population (Gebel 2000), and millions of people worldwide suffer from arsenic intoxication caused by drinking arsenic-contaminated water (National Research Council 2001).
Because these effects have been observed at current U.S. dietary exposures that constitute only 21% of PTWI for Cd (Egan et al. 2007), there is a need to investigate the relationship between Cd and osteoporosis and to reexamine the safe levels of Cd in food, the most common source of Cd exposure for the general population.
For instance, population registers, a common source of migration statistics, are used for a number of other administrative and statistical purposes.
Secondly, the recruitment of cases and control groups from separate population groups is another common source of bias in case-control studies.
Disorders of the rotator cuff (RC) are a common source of shoulder pain and disability especially in the elderly population [ 1].
They deliver significant individual and population benefit, but are also a common source of harm.
