This cohort spans the continuum of breast cancer risk, with some subjects at lower than average population risk.
The reported miscarriage rate of 5% (15/293 in the acupuncture in addition to usual care group, 6/147 in the sham acupuncture in addition to usual care group and 9/143 in the usual care only group) was lower than the population risk estimate of 11% in Australia, suggesting that acupuncture was not associated with a higher risk of miscarriage.
Higher Rn values indicate more potential transmission per new infection and they correspond to lower population immunity (i.e., higher risk of transmission).
A higher estimate of the population risk and a lower family history category were also associated with a greater overestimation of absolute risk.
In some of these populations, lower environmental risk exposure with lower CRC, incomplete case ascertainment and recording tools, as well as absence of large sample sets, are other challenges.
The data provided are restricted to women referred for coronary angiography and may therefore not be generalizable to patients at lower cardiovascular risk, population-based cohorts, and younger age-groups.
Our objective is to evaluate how different radon concentration thresholds are associated with the accuracy of ecological radon risk classification, geographic areas classified as higher or lower radon risk, populations classified as higher or lower risk, and visual temporal trends in lung cancer mortality.
Thus, a lower risk population may have been studied in the Stockholm trial, with lower exposure to MPA.
That study, recently published, confirmed the absence of efficacy in a lower risk population [ 7].
These extremes of age may represent a lower risk population with respect to cardiac disease, due to selection and survival bias.
