Subcortical volumes, frontal cortical thickness, and pro-inflammatory cytokines in schizophrenia versus methamphetamine-induced psychosis.

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
Schizophrenia is associated with alterations in subcortical volumes, cortical thickness and pro-inflammatory cytokines, that may correlate with clinical features. However, analogous work on methamphetamine-induced psychosis is lacking. This study examines subcortical volumes, frontal cortical thickness and pro-inflammatory cytokines in schizophrenia and methamphetamine-induced psychosis.Diagnosis and symptom severity were determined using the Structured Clinical Interview for Axis I Disorders and the Positive and Negative Syndrome Scale, respectively. Structural T1-weighted images were acquired using a 3-Tesla magnetic resonance imaging scanner. Serum peripheral cytokine concentrations were measured using a multiplex bead array.Schizophrenia (n = 36) and methamphetamine-induced psychosis (n = 27) participants showed decreased left amygdala volumes and frontal cortical thickness compared to healthy controls (n = 32). Schizophrenia participants had increased bilateral caudate, putamen, and nucleus accumbens volumes compared to controls, and greater right globus pallidus and nucleus accumbens volumes compared to the methamphetamine-induced psychosis group. No significant differences were found in cytokine levels between groups or associations with neuroimaging measures.The novel discovery of increased globus pallidus and nucleus accumbens volumes in schizophrenia group compared with methamphetamine-induced psychosis group may show important distinctions in the neurobiology between these conditions. Future investigations should employ larger sample sizes, incorporate longitudinal study designs, and integrate magnetic resonance spectroscopy which may show important neurometabolic signatures in these brain regions in methamphetamine-induced psychosis.
