Firstly the effect size is tiny. Doubt it’s significant. Do we need 2 more patients to develop dementia in the exposed group to make them the same?

Punchline: “Lithium-exposed patients were more likely to be married, cohabiting or in a civil partnership, to be a current/former smoker, to have used antipsychotics, and to have comorbid depression, mania/bipolar affective disorder (BPAD), hypertension, central vascular disease, diabetes mellitus, or hyperlipidemias.
