Halved Dose of Antipsychotics Versus High-Dose Antipsychotic Therapy for Relapse in Patients with Schizophrenia Receiving High-Dose Antipsychotic Therapy: A Randomized Single-Blind Trial.
Trial report in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Both a shortage and an excess of dopamine (DA) in the prefrontal cortex and striatum result in their decreased functions, and the relationship between the DA levels and their functions exhibits an inverted-U shape. Increased DA transmission via dose reduction in the currently used antipsychotics may improve the activation of DA-related symptoms in schizophrenia; these include delusions and auditory hallucinations caused by increased DA release. In this case, reducing the dose of the antipsychotic may be a treatment option for relapse in patients with schizophrenia who are already on high doses of antipsychotics and find it difficult to further increase the dose. A total of 54 inpatients with schizophrenia receiving high-dose antipsychotic therapy were randomly assigned to either the halved-dose group or the high-dose group (symptomatic treatment). The study compared the time from relapse to improvement between the two groups. In the halved-dose group, the period until relapse improvement ranged from 1 to 3 weeks, while the high-dose group experienced improvement in 4 to 9 weeks, and a significant difference was observed between the two groups using Kaplan-Meier survival analysis (
