Case-Control Studies-Reply.
Irony TZ. JAMA 2019. PMID 30806687
Case-control study design.
El-Masri MM. Can Nurse 2014. PMID 25345183
Retrospective studies and chart reviews.
Hess DR. Respir Care 2004. PMID 15447798 Free article.
A retrospective case series is the description of a group of cases with a new or unusual disease or treatment. With a case-control study, cases with and without the condition of interest are identified, and the degree of exposure to a possible risk factor is then retrospectively compared between the 2 groups. With a matched case-control study, control subjects are selected such that they resemble (match) the cases with regards to certain characteristics (eg, age, comorbidity, severity of disease). ...

Robust Tests for Additive Gene-Environment Interaction in Case-Control Studies Using Gene-Environment Independence.
Liu G, et al. Am J Epidemiol 2018. PMID 28633381 Free PMC article.
Using gene-environment independence enhances statistical power for testing multiplicative interaction in case-control studies. ...We study the impact of gene-environment association on the resultant test with case-control data. Our simulation studies suggest that the EB approach uses the gene-environment independence assumption in a data-adaptive way and provides a gain in power compared with the standard logistic regression analysis and better control of type I error when compared with the analysis assuming gene-environment independence. ...

Burning mouth syndrome and associated factors: A case-control retrospective study.
Chimenos-Küstner E, et al. Med Clin (Barc) 2017. PMID 27871766 Free article.
PATIENTS AND METHODS: 736 medical records of patients diagnosed of burning mouth syndrome and 132 medical records for the control group were studied retrospectively. ...

Using family members to augment genetic case-control studies of a life-threatening disease.
Chen L, et al. Stat Med 2016. PMID 26866629 Free PMC article.
Survival bias is difficult to detect and adjust for in case-control genetic association studies but can invalidate findings when only surviving cases are studied and survival is associated with the genetic variants under study. ...

Cohort studies: marching towards outcomes.
Grimes DA and Schulz KF. Lancet 2002. PMID 11830217
Observational studies, however, rarely achieve such a degree of similarity, so investigators need to measure and control for confounding factors. ...Variations on the cohort theme include the before-after study and nested case-control study (within a cohort study). Strengths of a cohort study include the ability to calculate incidence rates, relative risks, and 95% CIs. ...

Caries Experience in Children with and without Molar-Incisor Hypomineralisation: A Case-Control Study.
Grossi JA, et al. Caries Res 2017. PMID 28658675
METHODS: A case-control study was designed in which 130 children aged between 7 and 13 years with MIH (cases) were matched with 130 children without the condition (controls) according to age, sex, and school. ...

Association between stressful life events and autoimmune diseases: A systematic review and meta-analysis of retrospective case-control studies.
Porcelli B, et al. Autoimmun Rev 2016 - Review. PMID 26708168
INCLUSION CRITERIA: We included retrospective case-control studies that compared patients diagnosed with autoimmune disorders and controls regarding the incidence of stressful events occurring before diagnosis, and investigated said events with validated questionnaires. ...Only prospective studies can provide more certain inference about the causality of this relationship....
