Such interactions can be analysed from various perspectives, for example, common risk factors, common treatments, common prognosis; however, the primary perspective adopted here for the pupose of analysis is that of "common prognosis", by which is meant that the two conditions mutually influence prevalence, incidence, remission and mortality risk.
Simulation methods show our estimator to have reasonable statistical properties for estimates of the common risk under various scenarios for changes in risk over time.
Owing to a lack of data, our aim was to evaluate and compare the impact of various common neurological diseases on the risk for falls in independent community dwelling senior citizens.
Given that the C allele is associated with an increased risk of various common cancers and that the incidence of cancers generally rises with age (Nordling, 1953; DePinho, 2000; Cancer Research UK, 2010), it is an important finding that this well-powered multicohort study found that it was not associated with poorer outcomes for other aging phenotypes.
Most importantly, FCGR3A deficiency is associated with 2 distinct autoimmune diseases (SLE and RA), suggesting that defective FcγRIIIA functions may represent a common risk factor for various autoimmune diseases.
In human genomics, consortia and networks have rapidly emerged as important infrastructure for the discovery of genetic risk factors for various common diseases, especially for genome-wide association studies, which require very large sample sizes for discovery and replication (12, 13).
These data suggested that HLA-DRB1*1501 is a common risk allele for anti-GBM disease in various populations.
9 However, there is substantially less knowledge about the risk for falls in patients afflicted with various common neurological diseases.
A prominent example of a common risk factor between cardiovascular, cerebrovascular disease and various cancer entities is tobacco smoking.
On the other hand, evidence is also emerging that various common environmental chemical agents, including some endocrine disruptors, can affect normal developmental epigenetic processes and hence contribute to increase the risk of chronic disease in adults (Edwards and Myers 2007).
