relative risk reduction in recurrent Ml with dapagliflozin is comparable to other established therapies used in secondary prevention after MI...," Dr.
From the definitions above, we immediately see that the three measures have quite different ranges; both the
relative risk and odds ratio vary between 0 and ~, while the risk difference is limited to a much smaller interval between -1 and 1.
Major Finding: After adjusting for risk factors, the
relative risk for antidepressant medication for men with type 2 diabetes was 1.46; for women, it was 1.20 for ages 30-39.
Nevertheless, there seemed to be an inverse relation between the degree of homocysteine reduction and the
relative risk of stroke, with a significant reduction in the
relative risk of stroke occurring once a 20% decrease in homocysteine concentration had been reached.
Meyer and Meyer explain that the coefficients of absolute and
relative risk aversion developed by Pratt (1964) and Arrow (1965) were originally based on this specific concept of wealth, but because W is difficult to measure in practice, most subsequent analyses have used other forms of wealth or nonwealth variables as arguments of the decision maker's utility function.
When, in 1994, Janet Daling found that women have a 1.5
relative risk for breast cancer after abortion, the Journal of the National Cancer Institute, publishing her study, downplayed her results with an editorial noting, "In epidemiologic research,
relative risks less than 2 are considered small and ...
A plethora of published medical and scientific literature establishes a statistically significant increased
relative risk for adverse cardiovascular events associated with Vioxx use.
In addition, although the
relative risks are lower than those reported in other studies for infants born at earlier gestational ages, the much larger number of near-term infants affected would tend to make their poorer functioning at preschool and kindergarten a serious issue for national health policy, Dr.
Some studies use
relative risks (RRs) to describe results; others use odds ratios (ORs).
Often, assessments of "
relative risk" are colored by purely political considerations.
This article discusses the role of epidemiologic evidence in toxic tort cases, focusing on
relative risk. If a
relative risk is above 2.0, can we infer specific causation?
A statistical analysis found four independent predictors of progression to cirrhosis (severe scarring of the liver): absence of protease inhibitor therapy (
relative risk 4.74), heavy alcohol use (greater than or equal to 50 grams per day -- about 5 drinks a day --
relative risk 4.71), CD4 count under 200 (
relative risk 2.74), and age greater than 20 years at the time of hepatitis C infection (
relative risk 2.74).
