Multiple logistic regression analysis is used to estimate the relative risk in case control studies. The estimators obtained are valid when disease is rare. In this paper an estimator of relative risk in a case control study has been proposed using logistic regression results when the incidence of...
The results confirm that our approach is useful for estimating the relative risk function and odds ratio in case-control studies. 展开 关键词: Case-control Local likelihood Nonparametric regression Odds ratio Relative risk function DOI: 10.1016/j.jspi.2007.12.012 被引量: 6 ...
Therefore, when observing the incidence of adverse events in the most likely risk period (from 0 to 72 h post-injection for DTaP-IPV-Hib) versus a control period farther removed from vaccination, the HVE may mask increased adverse event risk associated with vaccine administration. We have ...
Subjects for whom an event occurred (case group) are often observed but generally analyzed in comparison to those for whom an event did not (control group); however, estimating relative risk using case group data without approximation is hindered. In this study, an obstacle to estimate relative...

It will be demonstrated that misclassification can also distort trends in relative risks. Real examples from the epidemiological literature are used for illustration.关键词: Case-Control Study Dose-Response Epidemiology Misclassification Odds Ratio Relative Risk ...
