What does a risk ratio of 0.8 mean?

A relative risk that is less than 1.0 indicates that there is a lower risk among the people in Group A. • If the relative risk were 0.8, people in Group A would be 20% less likely than people in all other groups to die from a cause.

What does a rate ratio of 0.8 mean?

Examples. RR of 0.8 means an RRR of 20% (meaning a 20% reduction in the relative risk of the specified outcome in the treatment group compared with the control group). RRR is usually constant across a range of absolute risks. But the ARR is higher and the NNT lower in people with higher absolute risks.

What does risk 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.

What does a relative risk of 0.9 mean?

A risk ratio greater than 1.0 indicates an increased risk for the group in the numerator, usually the exposed group. A risk ratio less than 1.0 indicates a decreased risk for the exposed group, indicating that perhaps exposure actually protects against disease occurrence.

What does a risk ratio of 0.6 mean?

In this hypothetical case, the RR is 0.6 (12 per cent ÷ 20 per cent = 0.6). 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.

Relative risk and risk ratios

What does a risk ratio of 0.75 mean?

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.

What does a risk ratio of 0.2 mean?

An OR of 0.2 means there is an 80% decrease in the odds of an outcome with a given exposure.

What is a good risk ratio?

How the Risk/Reward Ratio Works. In many cases, market strategists find the ideal risk/reward ratio for their investments to be approximately 1:3, or three units of expected return for every one unit of additional risk.

What does an odds ratio of .98 mean?

The reported odd ratio of 0.98 at less than 1 indicates that for every additional parameter of the tested independent variable, they were . 98 times likely to report the likelihood of the test question.

What does a relative risk of 2.8 mean?

Thus the relative risk of seizure when taking the specific medication is 2.8 (2.8 = 0.16 / 0.057). A person is 2.8 times more likely to have a seizure when taking the specific medication, but that is only a 0.103% increase in absolute risk (1 in 1000 increase in absolute risk).

Is 0.7 a good quick ratio?

A quick ratio of 1.0 is considered good. It means that the company has enough money on hand to pay its obligations. A ratio higher than 1.0 means that the company has more money than it needs.

Is 0.7 a high debt ratio?

In general, many investors look for a company to have a debt ratio between 0.3 and 0.6. From a pure risk perspective, debt ratios of 0.4 or lower are considered better, while a debt ratio of 0.6 or higher makes it more difficult to borrow money.

What does risk ratio of 1.1 mean?

In general: If the risk ratio is 1 (or close to 1), it suggests no difference or little difference in risk (incidence in each group is the same). A risk ratio > 1 suggests an increased risk of that outcome in the exposed group. A risk ratio < 1 suggests a reduced risk in the exposed group.

Is 0.8 a good current ratio?

As a general rule, a current ratio below 1.00 could indicate that a company might struggle to meet its short-term obligations, whereas ratios of above 1.00 might indicate a company is able to pay its current debts as they come due.

Is 0.8 equity ratio good?

Generally, a good debt-to-equity ratio is anything lower than 1.0. A ratio of 2.0 or higher is usually considered risky. If a debt-to-equity ratio is negative, it means that the company has more liabilities than assets—this company would be considered extremely risky.

What does a relative risk of 1.5 mean?

What relative risk tells us. A relative risk that is greater than 1.0 shows that there is an increased risk among the people in Group A. • This means if the relative risk was 1.5, people in Group A would be 50% more likely than people in all other groups to die from a cause.

How do you explain odds ratio in words?

An odds ratio (OR) is a measure of association between an exposure and an outcome. The OR represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure.

How do you explain odds ratio results?

The odds ratio tells us how much higher the odds of exposure are among case-patients than among controls. An odds ratio of • 1.0 (or close to 1.0) indicates that the odds of exposure among case-patients are the same as, or similar to, the odds of exposure among controls. The exposure is not associated with the disease.

What does an odds ratio of 0.1 mean?

From probability to odds

So a probability of 0.1, or 10% risk, means that there is a 1 in 10 chance of the event occurring.

What's an acceptable level of risk?

Definition(s): the level of Residual Risk that has been determined to be a reasonablelevel of potential loss/disruption for a specific IT system. (See Total Risk, Residual Risk, and Minimum Level of Protection.)

What is the most important risk ratio?

The most common ratios used by investors to measure a company's level of risk are the interest coverage ratio, the degree of combined leverage, the debt-to-capital ratio, and the debt-to-equity ratio.

What is an acceptable risk score?

Acceptable risk is the level of potential losses that a society or community considers acceptable given existing social, economic, political, cultural, technical and environmental conditions.

What does a relative risk of 0.4 mean?

Relative risk is an important and commonly used term. An RR of 1.00 means that the risk of the event is identical in the exposed and control samples. An RR that is less than 1.00 means that the risk is lower in the exposed sample. An RR that is greater than 1.00 means that the risk is increased in the exposed sample.

What is considered low risk?

Low Risk: A hazardous condition is unlikely to cause accidents, and even if it does, results in only negligible damage.

What does an odds ratio of 1.5 mean?

It means that the odds of a case having had exposure #1 are 1.5 times the odds of its having the baseline exposure. This is not the same as being 1.5 times as probable: odds are not the same as probability (odds of 2:1 against means a probability of 13).
