What does a risk ratio of 0.70 mean?
Digressing again, an RR of 1.30 means that the risk is increased by 30%, and an RR of 0.70 means that the risk is reduced by 30%. From the discussion in this section, we can understand why these values for increase and the decrease are not equal in magnitude.
What does a risk ratio of 0.6 mean?
Assuming there are no other factors that may confound the association, a risk ratio less than 1 indicates that the risk in the exposed (index) group is less than the risk in the unexposed or less -exposed (reference) group, and therefore, the exposure is preventive.
What does a relative risk of 0.3 mean?
An RR of, say, 0.3 can be expressed in plain English in many ways. It indicates that the risk is lowered to less than one-third; that the risk is reduced to 30%, that the risk is lowered by more than two-thirds, and that the risk is reduced by 70%.
What does a relative risk of 1.7 mean?
A relative risk of one implies there is no difference of the event if the exposure has or has not occurred. If the relative risk is greater than 1, then the event is more likely to occur if there was exposure. If the relative risk is less than 1, then the event is less likely to occur if there was exposure.

What is a risk rating of 7?
'7 - Very high risk' investor: likely to aim for the highest possible returns and accept the highest levels of risk, recognising that the investment value may fluctuate very widely, particularly over the short-term.
How to tell if relative risk is significant?
If the relative risk is greater than one, the smallest value that will be statistically-significant occurs when the lower-limit of the 95% confidence interval for a relative risk just touches unity (or when the lower limit of the 95% confidence interval for the natural log of the relative risk just touches zero).
What is 0.75 risk ratio?
2c) A risk ratio of 0.75 means there is an inverse association, i.e. there is a decreased risk for the health outcome among the exposed group when compared with the unexposed group. The exposed group has 0.75 times the risk of having the health outcome when compared with the unexposed group.
Can risk be greater than 1?
If the RR/OR/HR >1, and the CI does not include 1, events are significantly more likely in the treatment than the control group. If the RR/OR/HR <1, and the CI does not include 1, events are significantly less likely in the treatment than the control group.
What does an odds ratio of 1.4 mean?
Odds Ratio is a measure of the strength of association with an exposure and an outcome. OR > 1 means greater odds of association with the exposure and outcome. OR = 1 means there is no association between exposure and outcome. OR < 1 means there is a lower odds of association between the exposure and outcome.
What does an odds ratio of 0.7 mean?
If the Odds ratio is 0.7 then it indicates a protective effect - I.e a reduced odds of exposure in case vs control group. That reduced risk is 1-odds so will be 30 percent reduced risk fo exposure. statistical significance is linked to the p-value or CI- which we cannot infer from only the odds ratio.
What does a hazard ratio of 0.7 mean?
As a statistical measure, the hazard ratio can be difficult to interpret. For example, in a trial with a mortality outcome, a hazard ratio of 0.7 cannot be interpreted as a 30% reduction in the risk of mortality; rather, it means a 30% reduction in the rate of mortality (i.e., the time to mortality is slower).
What does a current ratio of 0.6 mean?
Current assets are in the numerator and current liabilities are in the denominator. So, the current ratio will show the current assets as a percentage of current liabilities. So, if the current ratio is 0.6; current assets are 60 percent of current liabilities.
What does a put call ratio of 0.70 indicate?
A falling put-call ratio, or below 0.7 and approaching 0.5, is considered a bullish indicator. It means more calls are being bought versus puts.
What is an acceptable risk ratio?
Determining Acceptability
In basic terms, any benefit-risk ratio greater than 1 is favorable (i.e., the benefit value is greater than the risk value).
What is a good risk ratio?
The risk/reward ratio is used by traders and investors to manage their capital and risk of loss. The ratio helps assess the expected return and risk of a given trade. In general, the greater the risk, the greater the expected return demanded. An appropriate risk reward ratio tends to be anything greater than 1:3.
What does a relative risk of 0.8 mean?
Conversely, a relative risk of 0.8 means that the risk in the exposed group is 20% lower than in the unexposed group.
What is risk 0.5% per trade?
0.5% Risk Per Trade: The Best Choice, But..
Many traders suggest risking 0.5% per trade, and yes, that's a good strategy. The thing is, risking 0.5% per trade means 20 losses blow your account, while risking 0.25% per trade means 40 losses blow your account. I think you get the point.
Should I use odds ratio or relative risk?
Odds ratios (OR) are commonly reported in the medical literature as the measure of association between exposure and outcome. However, it is relative risk that people more intuitively understand as a measure of association. Relative risk can be directly determined in a cohort study by calculating a risk ratio (RR).
What does a risk ratio of 1.07 mean?
A risk ratio of 1.07 means the outcome is 7 percent more likely to occur in the group it describes. In the 1999 study about gender and race bias in referrals for cardiac catheterization, a risk ratio of 0.93 could be used to say black patients were 7 percent less likely to be referred than white patients.
What is 0.75 ratio?
The answer is C 3:4.
What is a good relative risk score?
When a treatment has an RR greater than 1, the risk of a bad outcome is increased by the treatment; when the RR is less than 1, the risk of a bad outcome is decreased, meaning that the treatment is likely to do good.
How do you convert relative risk to percentage?
Relative risk reduction (RRR) is a convenient way of re-expressing a risk ratio as a percentage reduction: RRR = 100% × (1 – RR). For example, a risk ratio of 0.75 translates to a relative risk reduction of 25%, as in the example above.
What is relative risk calculated on?
Relative risk (RR) is: a ratio of proportions. RR = EER CER. A measure of the chance of the event occurring in the experimental group relative to it occurring in the control group.
Can relative risk be negative?
If Relative Risk is larger than 1, it is a positive association; exposure may be a positive risk factor. If Relative Risk is smaller than 1, it is a negative association; exposure may be a protective factor.
