Talk:Nested case–control study

Definition in the preamble to this article is wrong and misleading
"in a nested-case-control study, some number of controls are selected for each case from that case's matched risk set. By matching on factors such as age and selecting controls from relevant risk sets, the nested case control model is generally more efficient than a case-cohort design with the same number of selected controls." - No. That is called a matched case control study. A nested case-control is when controls are sampled from the same preexisting study population that the cases came from. Maybe you guys should've kept the plagiarized version because it was actually right. Change this BS as quickly as possible because this is misleading and frustrating for anyone who is trying to reconcile this nonsense with what is written in Epidemiology textbook and various peer reviewed articles. What a joke. Get your shit together wikipedia.

Completely Rewritten
Because the original article was plagiarized, a completely re-written and expanded article has replaced it. If the new article is considered insufficient, I strongly recommend removing the article altogether rather than revert to its previous plagiarized state. It is not acceptable for Wikipedia to host plagiarized material, especially after the offense has been noticed (the plagiarism was pointed out in September 2010 and remained on the site until August 2011). — Preceding unsigned comment added by 209.94.133.165 (talk) 23:06, 19 August 2011 (UTC)

 * True. Almost all of the text in this article so far has been lifted from that article. I would suggest that the reference is cited and the text edited appropriately.Jimjamjak (talk) 11:56, 2 August 2011 (UTC)

Nested Case Control Study
Case control study design has many benefits however it may be a less tedious process when used in conjunction with an ongoing cohort study. For instance a study on the levels of HDl cholesterol associated with cardiovascular disease would yield the results in the form of an odds-ratio only when using a case-control study.

In a case-control study, two populations are compared, for instance,in a cardiovascular clinic: patients with a cardiovascular event and patients without a cardiovascular event (as diagnosed by the attending physician and the consultant cardiologist).

However if one wants to determine that association within one population it is more economical and TIME SAVING to use the data collected from a cohort study. Thus first collecting alll the patient information for example blood pressure and lipid profile, it would be wise to collect the information leading to a cohort of patients.

NIH
"To advance its prevention research agenda, NIH might be encouraged to maintain a registry of new and existing cohorts, with an inventory of data collected for each; to foster the development of specimen banks; and to serve as a clearinghouse for information about optimal storage conditions for various types of specimens." I don't really see the need to write about this here. It would appear to be a suggestion (or the result of some primary research), which is out of place in WP. Deleting as (I think) appropriate.

Example of a nested case control
This page uses the following study as an example of a nested case control. I do not believe this is a nested case control, but is a cohort study. The study itself does not call itself a nexted case control or a case control: Hankinson SE, Colditz GA, Manson JE, Willett WC, Hunter DJ, Stampfer MJ, Speizer FE. A prospective study of oral contraceptive use and risk of breast cancer (Nurses' Health Study, United States). Cancer Causes Control. 1997 Jan;8(1):65-72. PMID: 9051324
