Importance Patients with dementia may be at an increased suicide risk. Identifying groups at greatest risk of suicide would support targeted risk reduction efforts by clinical dementia services. Objectives To examine the association between a dementia diagnosis and suicide risk in the general population and to identify high-risk subgroups. Design...

Objective To examine the relative risk of suicide mortality in patients with Huntington’s disease (HD). Methods A case–control study design was used. We used linked electronic records from primary care, secondary care and Office for National Statistics from England from 2001 through 2019. Controls were matched to cases by general practice and suic...

Using multiple linked electronic health databases, we conducted a large case-control study in England from 2001 through 2019 to examine the association between ethnicity and suicide risk. Asian, Black and Other ethnic groups had a significantly lower suicide risk compared to White individuals, with those of Asian ethnicity having the lowest risk (O...

Question
Hello,
I am trying to adjust for the confounding effect of a third variable on the association between ethnicity (has multiple categories) and death (binary). I am using fixed effect conditional logistic regression to build multivariable model. I know that for a factor to be considered an important confounder it has to change the crude odds ratio by more than 10% (besides the other criteria of being associated with the exposure and outcome).
However, in case I have many categories for the exposure, how can I know if a third factor is an important confounder? Should it change the odds ratio of "ALL CATEGORIES" by 10% or more, or even a change in "one out of all categories" makes it an important confounder? or is there another more appropriate way to deal with the situation?
Question
Hello,
I am conducting a case-control study for suicide where controls are matched to cases on the date of the suicide death (index date), hence, risk-set sampling. An electronic medical database is employed for the purpose of the study. When assessing the exposure, e.g. self-harm, should I consider the exposure at any point in the patient's clinical course or only up to the date of suicide death/index date? To elaborate, while cases die and do not contribute further to the database, controls remain for some time later contributing to more information. Shall I account for that information or stop at the index date?
