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
Objective: This study aims to explore the cognitive impairment characteristics, psychotic symptoms, and the relationship with alterations in cortical thickness in involuntarily hospitalized, first-episode, drug-naive schizophrenia patients. Methods: A total of 59 involuntarily hospitalized patients and 60 healthy controls were included. The MATRICS Consensus Cognitive Battery (MCCB) scale was used to evaluate cognitive function in involuntarily hospitalized patients and healthy controls. The Positive and Negative Syndrome Scale (PANSS) was utilized to evaluate psychotic symptoms in involuntarily hospitalized patients. Structural MRI scans were obtained from all participants, and the Desikan-Killiany template was used in FreeSurfer software to extract the cortical thickness values. Results: Involuntarily hospitalized patients exhibited cognitive impairments across seven cognitive domains compared to healthy controls. Additionally, these patients exhibited increased cortical thickness in the right temporal pole, left posterior cingulate gyrus, and left temporal pole compared to controls. Partial correlation analysis revealed that in the involuntarily hospitalized patients, the left posterior cingulate gyrus had a negative correlation with general symptoms, while the right temporal pole showed a positive correlation with negative symptoms. No correlation was found between cortical thickness and cognitive function in patients with involuntary hospitalization. In contrast, within the healthy control group, both the left and right temporal poles exhibited positive correlations with reasoning and problem-solving abilities. Conclusions: Our study reveals significant cognitive impairments and cortical thickness alterations in first-episode, drug-naive schizophrenia patients during their initial involuntary hospitalization. These cortical thickness alterations were significantly associated with psychotic symptoms, but not cognitive impairment. These findings suggest that cognitive dysfunction and symptom presentation in early-stage schizophrenia patients with involuntary hospitalization may be influenced by distinct neuroanatomical mechanisms.
