CohortEPIDEMIOLOGYStudies the epidemiology of childhood cancer using case-control and cohort methods of investigation. Differences in the two methods; Calculation of odds ratio in case-control study and relative risks in cohort study; Advantages and disadvantages of the two methods.Bell...
Case-cohort design is a cost-effective sampling design approach for censored survival outcomes.It may be viewed as a special case of the more general two-phase sampling designs under certain conditions.In this talk,I will discuss the similarities and differences between these two approaches,particula...
In contrast, the C3PO sampling design is readily amenable to an array of epidemiologic analyses (e.g., cross-sectional, retrospective cohort, case-control). Our findings also imply that deep learning models applied to unstructured data have the potential to substantially reduce missingness, another ...
We compared the predictive performances of gender score versus biological sex in predicting TBI-related outcomes (early mortality and discharge location) using the test set. To achieve this, we considered the following three models for each outcome: Model 1 with binary sex and control variables as...
An asymptotically unbiased estimator of exposed versus non-exposed odds ratio from reported dose-response data Summary effect measures in meta-analysis of published epidemiological cohort or case control studies are often based on odds ratios reported for several ex...

Secondary objectives were to examine the correlation between EOS scores versus neonatal infection markers (CRP and WCC). By first establishing the local incidence of culture-proven EOS, the EOS calculator can then be applied to each individual case sample and the recommended management pathway cross-...
Particularly problematic are case-control studies that enroll patients on the basis of the current disorder in their mental disorder life history (unaware of other past and future disorders) and compare them against currently well controls (who may have been unwell in the past and may become ...
OBJECTIVES: It is still debated if pre-existing minority drug-resistant HIV-1 variants (MVs) affect the virological outcomes of first-line NNRTI-containing ART.METHODS: This Europe-wide case-control study included ART-naive subjects infected with drug-susceptible HIV-1 as revealed by population seq...
Using methods developed for family studies, we performed a case-control genome wide association study (GWAS) of elimination due to behavioral observation and testing results in a cohort of 528 Labrador Retrievers (2002–2013). We accounted for relatedness by including the pedigree as a covariate ...
Significant sex differences were also found in two big CRC screening trials, with 7% of women versus 11–13% of men between 50 and 65 having AA15,33. Also, differences in sensitivity and specificity of fecal occult blood tests were found—with men showing a higher sensitivity and positive pr...
