However, the risk ratio often provides a more transparent interpretation of the exposure-outcome association than the odds ratio. Modified Poisson regression has been proposed to directly estimate adjusted risk ratios and produce confidence intervals with the correct nominal coverage when individual-level ...
(DOC 66 kb) Abbreviations aHR, adjusted hazard ratio; aOR, adjusted odds ratio; APACHE, Acute Physiology and Chronic Health Evaluation; BMI, body mass index; ICU, intensive care unit; SAPS, Simplified Acute Physiology Score; SOFA score, Sepsis-related Organ Failure Assessment score; TNF, tumor...
Using data from two studies with health-related outcomes in children, we discuss the interpretation of the measures of association and their implications. Results The results from data analysis highlighted major differences between estimated OR and PR. Results from simulation studies indicate an improved...
However, the association of ECF did not remain significant after further adjustment for BMI and other variables, whereas the association of the ratio of ECF to BMI remained significant after the multivariable adjustment. As the ratio of ECF to BMI increased by 1 s.d., the odds ratio (OR) ...
After propensity adjustment, Impella use was associated with improved survival (odds ratio [OR] 1.55, 95% confidence interval [CI] 1.02 to 2.36) and less MI (OR 0.29, 95% CI 0.18 to 0.46) and cardiogenic shock (OR 0.54, 95% CI 0.39 to 0.74). Stroke, bleeding requiring transfusion, ...
The primary efficacy parameter is the odds ratio comparing FEVAR to both open repair and off label EVAR. For OSA, conservative 57 estimate of 8% peri-operative death might be expected, and a reduction to 4 % could be 58 considered clinically relevant, which is equivalent to an odds ratio...
(died-in-icu); that is, a face-value interpretation of the β mortality coefficient was problematic. endogeneity may also be suspected in mortality models where length of stay [ 7 ] or mortality probability [ 83 ] are entered as predictive covariates. such regression of a variable upon its ...
One of the benefits of the suggested approach is that the three components of the mixture model provide the analyst with a three-way interpretation, by estimating (i) the factors that predict the occurrence of a loss, (ii) the factors that influence the size of the resulting loss amount, ...

However, we remain cautious when it comes to interpretation of this analysis. This is a post-hoc analysis and cannot change the results of the original trial, though it allows us to better understand them. In particular, adjusting for post-treatment variables violates the randomisation principle ...
