The effects of lurasidone on five symptom domains and individual items in schizophrenia: Post-hoc analysis from Phase 3 study.
Trial report in International clinical psychopharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 aim of this analysis was to examine the impact of treatment with lurasidone on a broad range of symptoms during an acute episode of schizophrenia. In patients with an acute exacerbation of schizophrenia treated with lurasidone in a 6-week, double-blind, placebo-controlled trial, a mixed-effect model for repeated measures was used to analyze weekly change in both the five Marder Factors and the 30 individual items of the Positive and Negative Syndrome Scale (PANSS). Treatment with lurasidone was associated with significant endpoint improvement on all five Marder PANSS factors with effect sizes ranging from 0.22 to 0.44. Significant early (week 2), sustained improvement was observed on four of the five Marder Factors, with significant improvement occurring by week 4 on the Marder Negative Symptom factor. In addition to significant improvement on five out of eight Marder Positive Symptom items, the following non-Positive PANSS items were notable for being especially responsive to lurasidone treatment in terms of significant early improvement and endpoint effect sizes >0.3: anxiety, tension, preoccupation, active social avoidance, and conceptual disorganization. The results of this non-USA study confirm results from previous studies indicating that lurasidone is an effective antipsychotic medication.
