Odds versus relative risk
Odds versus relative risk- Risk vs odds The terms 'risk' and 'odds' are often used interchangeably but they actually have quite different implications and are calculated in different ways Odds is a concept that is very familiar to gamblers It is a ratio of probability that a particular event will occur and can be any number between zero and infinity For instance, odds are a symmetric measure, meaning that while risk only examines outcomes given interventions, odds can also examine interventions given outcomes Thus, a study can be constructed where, rather than choosing trial groups and measuring outcomes, outcomes can be chosen, and other factors can be analyzed

An odds ratio of 05 would mean that the exposed group has half, or 50%, of the odds of developing disease as the unexposed group In other words, the exposure is protective against disease Is odds ratio a measure of risk?Common pitfalls in statistical analysis Odds versus risk In biomedical research, we are often interested in quantifying the relationship between an exposure and an outcome "Odds" and "Risk" are the most common terms which are used as measures of association between variables Note that an odds ratio is a good estimate of the risk ratio when the outcome occurs relatively infrequently (

So for very rare alleles, the ratio of minor allele frequencies is pretty close to the odds ratio, while it's not necessarily a good approximation of the risk ratio, which anyway isn't a figure you want For genetics and genomics, unless you ascertained people on genotype at a young age, the figure you're interested in is the odds ratio You know the difference between risk and odds A risk is the proportion of subjects with an event in a total group of susceptible subjects Thus, we can calculate the risk of having a heart attack among smokers (infarcted smokers divided by the total number of smokers) and among nonsmokers (the same, but with nonsmokers)See all my videos at https//wwwzstatisticscom/videos/Health Stats IQ playlisthttps//youtubecom/playlist?list=PLTNMv857s9WUI5YsQMW14trmbopjZMWPa000 Int

When the disease is rare, the odds ratio will be a very good approximation of the relative risk The more common the disease, the larger is the gap between odds ratio and relative risk In our example above, p wine and p no_wine were 0009 and 0012 respectively, so the odds ratio was a good approximation of the relative riskRELATIVE RISK AND ODDS RATIO The relative risk (also known as risk ratio RR) is the ratio of risk of an event in one group (eg, exposed group) versus the risk of the event in the other group (eg, nonexposed group) The odds ratio (OR) is the ratio of odds of an event in one group versus the odds of the event in the other groupRather the odds is threefold greater

Odds can be expressed as a ratio of the probability an event will happen divided by the probability an event won't happen Odds in favor of A = A / (1 A), usually simplified to lowest terms, For instance, if the probability of an event occurring is 075, then the odds for it happening are 075/025 = 3/1 = 3 to 1 for, while the probability that it doesn't occur is 1 to 3 against9224 Measure of absolute effect the risk difference The risk difference is the difference between the observed risks (proportions of individuals with the outcome of interest) in the two groups (see Box 92a)The risk difference can be calculated for any study, even when there are no events in either group The risk difference is straightforward to interpret it describes the actualOdds versus risk Priya Ranganathan, Rakesh Aggarwal1, C S Pramesh2, Department of Anaesthesiology, Tata Memorial Centre, 1Department of Gastroenterology, Sanjay Gandhi

The odds ratio will estimate the average change in odds (the average odds ratio) among exposed individuals only when all individual odds ratios are equal and all individual outcome risks without exposure are equal 1;The difference between odds and risk is small when the event is rare (as illustrated in the first example above where a risk of 0091 was seen to be similar to an odds of 01) When events are common, as is often the case in clinical trials, the differences between odds and risks are large Risk Ratio vs Odds Ratio Whereas RR can be interpreted in a straightforward way, OR can not A RR of 3 means the risk of an outcome is increased threefold A RR of 05 means the risk is cut in half But an OR of 3 doesn't mean the risk is threefold;

Both the odds ratio and the risk ratio are valid measures of association;Odds vs Risk by Rukmini Kumar In many clinical papers, probabilities are reported both as 'risk ratios' and 'odds ratios' to indicate similar things However, they are not calculated similarly In this blog, I'll review the basic concepts behind these and examine how they differ with an example The relative risk of losing weight by choosing diet A over diet B is 1125, while the odds ratio is about 225 The reasons a medical article might choose one method of reporting over the other are complex, but the message here is that sorting that out starts by being clear about the difference between probability and odds

Percent decrease = (1 – Risk Ratio upper bound) x 100 It's worth stating again when comparing two proportions close to 1 or 0, the risk ratio is usually a better summary than the raw difference Odds Ratios We now turn to odds ratios as yet another way to summarize a 2 x 2 table Odds are another way of expressing the likelihood of RISK AND ODDS DEFINITIONS "Risk" refers to the probability of occurrence of an event or outcome Statistically, risk = chance of the outcome of interest/all possible outcomes The term "odds" is often used instead of risk "Odds" refers to the probability of occurrence of an event/probability of the event not occurringThe risk ratio In practice, risks and odds for a single group are not nearly as interesting as a comparison of risks and odds between two groups For risk you can make these comparisons by dividing the risk for one group (usually the group exposed to the risk factor) by the risk for the second, nonexposed, group This gives us the risk ratio

As a ratio of odds It is for instance common to describe an OR of "2" in terms of a "twofold risk" of developing a dis ease given exposure This inaccuracy entails potentially seri ous problems For example, OR = Odds in treated group / Odds in Placebo group When P1 and P0 are small, OR can be used to estimate RR However, then P1 and P0 are close to 05, the OR is typically much larger than RR Steve Simon wrote an excellent web page about the comparison of Odds Ratio versus Relative Risk
