Serum High Mobility Group Box Protein-1 Levels in Schizophrenia During Acute Psychotic Episodes and Remission.

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: High mobility group box-1 (HMGB1) is a non-histone protein that plays a role in neuroinflammation by inducing cytokines. We aimed to compare HMGB1 levels in patients with schizophrenia in both acute exacerbation and remission phases and in healthy controls and to determine whether HMGB1 correlates with symptom severity and C-reactive protein (CRP), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and monocyte/lymphocyte ratio (MLR). Methods: The study included 31 schizophrenia patients in remission and 31 schizophrenia patients hospitalised for acute psychotic exacerbation and 30 healthy controls. Serum HMGB1 levels were measured by enzyme-linked immunosorbent assay (ELISA). Brief Psychiatric Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), and Clinical Global Impression Scale (CGI) were used to assess symptom severity. Results: Serum HMGB1 levels were found to be significantly higher in both the remission group (140.48±63.52 pg/ml) and the acute exacerbation group (125.92±48.71 pg/ml) compared to healthy controls (57.44±13.04 pg/ml) (p<0.05). There was no statistically significant difference in serum HMGB1 levels between patients in remission and patients in acute psychotic exacerbation. There was no correlation between serum HMGB1 levels and severity of symptoms. No significant correlation was found between serum HMGB1 levels and other inflammatory markers. There was a statistically significant negative correlation between serum HMGB1 levels and chlorpromazine-equivalent antipsychotic doses (rs=-0.316, p=0.047). Conclusions: Our findings suggest that HMGB1 levels are elevated in individuals with schizophrenia, regardless of phase, which may reflect trait-like characteristics of the disorder. However, further research is needed to confirm this. Increased HMGB1 may contribute to schizophrenia pathogenesis through neuroinflammation.
