Differential structural cortical correlates of positive, negative, and linguistic control formal thought disorder dimensions in schizophrenia.

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
Formal thought disorder (FTD) is a core symptom of schizophrenia. The pathophysiology of FTD is still unclear. We focus on multiple cortical measures to capture the exact nature of brain alterations (e.g., plasticity, early brain development) in FTD dimensions. We included 70 schizophrenia patients. We assessed FTD, acquired structural neuroimaging scans, and analyzed cortical thickness, volume, surface area, and local gyrification (IGI). Results reveal negative FTD to be associated with different structural brain correlates compared to the positive and linguistic control FTD dimensions most prominent in markers of early brain development. Severity of positive and linguistic control FTD dimensions correlated positively with IGI of core language regions including temporal, Heschl's, and inferior frontal gyri. Severity of negative FTD dimension was inversely correlated with lGI of occipital and parietal regions. Findings propose distinguishable changes most prominent in markers of early brain development associated with FTD dimensions suggesting a distinct pathophysiology.
