3.3 SSRI concentration at follow-up visit & fall risk
The results of the association between plasma concentrations of SSRIs at follow-up and fall risk prior study visit are presented in Supporting information Table S3. An increased fall risk was found for users with concentrations in the middle tertile compared to users with the lowest concentrations (OR 4.67, 95% CI 1.09-19.9). However, after adjusting for confounders this association disappeared.
