Incidence rate ratio interpretation stata
Exponentiated coefficients (odds ratio, hazard ratio); Marginal effects coefficients (aka odds ratio in logistic regression, harzard ratio in the Cox model, incidence rate ratio, Tables containing the signs of the coefficients, " significance stars", A rate ratio in epidemiology, is a relative difference measure used to compare the incidence rates of events occurring at any given point in time. A common predicted counts, or an incidence rate ratio (using Stata's terminology) or a relative risk. (using Agresti's terminology) of 7.4 compared to the cells that have X1=0. Additionally, you can use lincom to calculate odds ratios and incidence-rate ratios between sets of covariates. The below example based out of [R]lincom should
23 Oct 2017 Stata also has a poisson command, which is modelled using a full maximum likelihood algorithm. of count model coefficients results in incidence rate ratios. The statistic The interpretation of the rate ratios can be given as:.
14 Oct 2011 For such a model STATA can produce exponentiated coefficients. According to the help file such coefficients can be interpreted as incidence-rate 6 Jul 2010 The usage and relative merits of the incidence rate ratio (IRR) and the incidence For analysis of a single quantitative exposure variable or multiple Table 5 shows the results of the multivariable analyses (STATA codes I am going to implement the analysis the way you have prposed. I will come What is the difference between incident rate ratio IRR and Odds ratio? Question. 30 Apr 2015 A related effect size, the pooled incidence rate ratio (IRR), is instead based on We used Stata 13.1 [25] to generate the data and estimate incidence rate, risk, risk difference, risk factor, relative risk, odds ratio. Introduction STATA permits the analyst to perform elementary epidemiological analysis. 23 Oct 2017 Stata also has a poisson command, which is modelled using a full maximum likelihood algorithm. of count model coefficients results in incidence rate ratios. The statistic The interpretation of the rate ratios can be given as:. 30 Jul 2015 These are readily-obtained using the SAS, Stata and R statistical software packages. Standardized risk or prevalence ratios and differences are readily risks or standardized prevalences) retains its intended meaning: it is

Study 2 states (or reports) a rate ratio of 11.7 in the paper. Study 2 : the incidence is 5.7/100,000/year in the general population (n=19,855,283). The study gives the number of events in the general population as 6276. The events in the patient group is 37, with an incidence of 66.8/100,000.The study reports a rate ratio of 11.7. The risk ratio is estimated as 1.43, and because the dataset is large, the 95% confidence interval is quite narrow. Estimating risk ratios from observational data. Let us now consider the case of observational data. To do so we simulate a new dataset, where now the treatment assignment depends on x: clear set seed 1234 set obs 10000 gen x

Explore Stata's survival analysis features, including Cox proportional hazards, competing-risks regression, parametric survival models, features of survival models, and much more. Watch How to calculate incidence rates and incidence-rate ratios. A survival example session. Additional resources.
