RR . Relative risk or RR is very common in the literature, but may represent: . a risk ratio, ; a rate ratio, ; a prevalence ratio, or ; even an odds ratio; There can be substantial difference in the association of a risk factor with . prevalent disease versus ; incident disease; In the general medical literature, rate is often incorrectly used for prevalence measures.

The difference between odds ratio and risk ratio. May 15, 2014 • ericminikel. The other day I was emailing with a statistical genetics colleague about a rare SNP associated with a phenotype. I stated that the minor allele frequency (MAF) was .07% in cases and .01% in controls, for a risk ratio of 7. After clicking send, I felt a twinge of regret.

Measures of relative effect express the outcome in one group relative to that in the other.

For estimates of odds ratios, this is logit (ie the logarithm of the odds of the mean); for estimates of relative risk ratios, this becomes logarithm. We can specify this manually, or just use a built-in family for our generalized linear model for which the logarithm is the canonical link fucntion, and hence the default. More on the Odds Ratio Ranges from 0 to infinity Tends to be skewed (i.e. not symmetric) “protective” odds ratios range from 0 to 1 “increased risk” odds ratios range from 1 to Example: “Women are at 1.44 times the risk/chance of men” “Men are at 0.69 times the risk/chance of women” 2020-09-28 · The ratio of these is the risk ratio, a relative measure of association.

Most readers perceive it as relative risk (RR), although most of them do not know why that Odds ratio vs risk 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 non-smokers (the same, but with non portantly, we see that the odds ratio is close to the relative risk if probabilities of the outcome are small (Davies et al., 1998).

The basic difference is that the odds ratio is a ratio of two odds (yep, it’s that obvious) whereas the relative risk is a ratio of two probabilities. (The relative risk is also called the risk 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 non-smokers (the same, but with non portantly, we see that the odds ratio is close to the relative risk if probabilities of the outcome are small (Davies et al., 1998). And it is this fact that enables us, most of the time, to approximate the relative risk with the odds ratio. Table 5 below illustrates the relationship between RR and OR for some probabilities of the outcome. In general conversation, risk and odds are used interchangeably.
