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
introductionPeople with Lewy body dementia (LBD) experience pronounced psychotic symptoms but are extremely sensitive to side effects from antipsychotic treatment. In comparison, acetylcholinesterase inhibitors (AChEIs) are a safer treatment option for managing cognitive and neuropsychiatric symptoms and should ideally be the first-line treatment according to review literature. This study described the pharmacological treatment of LBD-associated neuropsychiatric symptoms among older people by comparing dispensing records of antipsychotic drugs and AChEIs.
methodsThis study included people with records of antipsychotic drugs dispensed in 2019 according to the Swedish Prescribed Drug Register, which functioned as an indicator of neuropsychiatric symptoms, who had been registered with LBD in the Swedish registry for cognitive/dementia disorders according to basal registrations from 2007 to 2020. We then determined the proportions of individuals with and without dispensing records of AChEIs prescribed before their index antipsychotic prescription fill of 2019, by comparing prescribing dates. Age, sex and nursing home residency were included as independent variables in a multiple logistic regression model to analyse associations between demographic factors and first-line treatment with AChEIs.
resultsIn total, 362 individuals with symptoms of LBD had filled at least one prescription for any antipsychotic drug in 2019. There were 114 people (31.5%) who had been prescribed antipsychotics as first-line treatment instead of AChEIs, and among them, 60 individuals had been diagnosed with LBD after the index antipsychotic prescribing date. First-line treatment with AChEIs was more common among males (odds ratio, OR, 1.65 [95% CI 1.03-2.62]) and nursing home residents (2.51 [1.59-3.96]).
conclusionsAntipsychotics were utilized as first-line treatment instead of AChEIs among almost one-third of antipsychotic users with symptoms of LBD. It is important to consider emerging psychotic symptoms among older people as possible manifestations of LBD to ensure early and appropriate pharmacological treatment.
