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;Risk, and related measures of effect size (for categorical outcomes) such as relative risks and odds ratios, are frequently presented in research articles Not all readers know how these statistics are derived and interpreted, nor are all readers aware of their strengths and limitations risk = odds/ (1odds) "Most published research providing an odds ratio as a measure of effect size should also provide sufficient information for the baseline risk, and hence the relative risk, to be calculated If numbers in each group are given, the crude relative risk can be calculated directly" – BMJ 14;348f7450 doi /bmj

Odds Ratio versus Relative Risk Since it is a ratio of ratios, the odds ratio is very difficult to interpret The relative risk is easier to interpret, so the odds ratio alone is not very helpful However, there are certain commonly occurring situations in which the estimate of the relative risk is not very good,About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How works Test new features Press Copyright Contact us Creators Relative risks versus odds ratios Researchers investigated the effectiveness of a probiotic drink containing Lactobacillus for the prevention of any diarrhoea associated with antibiotic use in hospital

The relative risk and the odds ratio are measures of association between exposure status and disease outcome in a population When to use the odds ratio or the relative risk? These two measures are the odds ratio and relative risk Both are two different statistical concepts, although so much related to each other Relative risk (RR) is simply the probability or relationship of two events Let's say A is event 1 and B is event 2

 Odds ratios While risk reports the number of events of interest in relation to the total number of trials, odds report the number of events of interest in relation to the number of events not of interest Stated differently, it reports the number of events to noneventsThe relative risk reduction of %Obviously, the odds reduction of 25% What will be your second choice?

The absolute risk is the probability of an event in a sample or population of interest The relative risk (RR) is the risk of the event in an experimental group relative to that in a control group The odds ratio (OR) is the odds of an event in an experimental group relative to that in a control group An RR or OR of 100 indicates that the risk is comparableThe relative risk is best estimated using a population sample, but if the rare disease assumption holds, the odds ratio is a good approximation to the relative risk — the odds is p / (1 − p), so when p moves towards zero, 1 − p moves towards 1, meaning that the odds approaches the risk, and the odds ratio approaches the relative riskOdds Ratio versus Relative Risk Odds ratio can be calculated in a cohort study and in a casecontrol study − The exposure odds ratio is equal to the disease odds ratio Relative risk can only be calculated in a cohort study 33 When Is Odds Ratio a Good Estimate of Relative Risk?

 INTRODUCTION Odds ratio (OR) and risk ratio (RR) are two commonly used measures of association reported in research studies In crosssectional studies, the odds ratio is also referred to as the prevalence odds ratio (POR) when prevalent cases are included, and, instead of the RR, the prevalence ratio (PR) is calculated 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 (TheThis implausible scenario is shown in Table 5, where collapsed counts for low (or high) risk subjects only produce a 2 × 2 table with an odds ratios of 400
