Duration of new antidepressant use and factors associated with discontinuation among community-dwelling persons with Alzheimer's disease.
Article in European journal of clinical pharmacology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeTo study how long antidepressants initiated after diagnoses of Alzheimer's disease (AD) were used and factors associated with discontinuation of use among persons with Alzheimer's disease (AD). In addition, differences in duration of use between the antidepressants groups were compared.
methodsRegister-based Medication use and Alzheimer's disease (MEDALZ) cohort included 70,718 community-dwelling people with AD who were diagnosed during the years 2005-2011. For this study, the new antidepressant users were included after 1-year washout period (N = 16,501; 68.6% females, mean age 80.9). The duration of antidepressant use was modeled with the PRE2DUP method. Factors associated with treatment discontinuation were assessed with Cox proportional hazard models and included age, gender, comorbid conditions and concomitant medications.
resultsMedian duration of the new antidepressant use period was 309 days (IQR 93-830). For selective serotonin reuptake inhibitor (SSRI) use, the median duration was 331 days (IQR 101-829), for mirtazapine 202 days (IQR 52-635), and for serotonin and norepinephrine reuptake inhibitors (SNRIs) 134 days (IQR 37-522). After 1-year follow-up, 40.8% had discontinued antidepressant use, 54.6% after 2 years and 64.1% after 3 years. Factors associated with treatment discontinuation were age over 85, male gender, diabetes, and use of memantine, opioids, and antiepileptics whereas benzodiazepines and related drugs and antipsychotic use were inversely associated with discontinuation.
conclusionsAntidepressants are used for long-term among people with AD. Need and indication for antidepressant use should be assessed regularly as evidence on their efficacy for behavioral and psychological symptoms of dementia is limited.
