Trends in Antipsychotic Polypharmacy and Potential Overtreatment with Antipsychotics: A Naturalistic Cohort Study of People in Long-term Care.
Article in Schizophrenia bulletin, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundDue to the side effects of antipsychotics, overtreatment is an important concern. Previous research focused on antipsychotic polypharmacy and excessively high doses. In this study, the aim is to map changes over the years in potential overtreatment, antipsychotic polypharmacy, total antipsychotic dose, and subjective side effect burden. Moreover, the association of the total dose and antipsychotic polypharmacy with the subjective side effect burden will be investigated. STUDY
designData from a naturalistic longitudinal cohort were used (PHAMOUS, 2013-2021). Potential overtreatment was defined as a antipsychotic dose equivalent to > 5 mg risperidone or antipsychotic polypharmacy, in combination with a high subjective side effect burden. Mixed effect models were used to investigate trends in potential overtreatment, antipsychotic polypharmacy, total antipsychotic dose, and subjective side effect burden and to assess the association of total dose and antipsychotic polypharmacy with subjective side effect burden. STUDY
resultsOverall, 15,717 observations nested in 5,107 participants were used. One-third of the participants were potentially overtreated, which did not change over time. The prevalence of a dose above the equivalent of 5 mg risperidone decreased, antipsychotic polypharmacy prevalence increased, and the subjective side effect burden decreased. A higher dose and antipsychotic polypharmacy were associated with higher subjective side effect burden.
conclusionPotentially overtreated patients should be revaluated to assess whether changes are needed. To assess whether a patient is truly overtreated, their clinical history, number of relapses, patients' preferences, overall functioning, previous attempts to reduce antipsychotic treatment, and previous severity of disease should be taken into account.
