Impact of Antidepressant Use on the Trajectory of Alzheimer's Disease: Evidence, Mechanisms, and Therapeutic Implications.
Review in CNS drugs, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The relationship between antidepressants and Alzheimer's disease (AD) is very complex, and the literature is mixed regarding the effect of these medications on the trajectory of the disease. This paper reviews findings from relevant clinical studies that have assessed the impact of antidepressants on AD onset and disease progression. To date, these medications seem to attenuate the risk of developing the disease without affecting the rate of progression. However, most evidence stems from observational studies that are subject to methodological bias. Serotonergic antidepressants are thought to affect AD pathophysiology by reducing β-amyloid (Aβ) plaque formation and promoting hippocampal neurogenesis. However, the mechanisms underlying their effect need to be examined further, especially in humans. Moreover, more robust clinical studies in terms of design (randomized controlled trials) and longer duration of follow-up are needed. Variables, including depression timeline/onset and its clinical course, apolipoprotein E4 (APOE4) genotype status, sex, dose/duration of antidepressant treatment, and AD biomarkers need to be incorporated in future trials to better elucidate the effect of antidepressants on AD risk.
