1 · What the graph read from it

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.

2 · The registry

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

backgroundGlucuronic acid (GlcA) is crucial in the glucuronidation pathway, facilitating the metabolism and elimination of various substances and drugs. Recent studies have noted elevated GlcA levels in patients with schizophrenia (SCZ) compared with healthy individuals. However, it remains unclear whether this elevation contributes to SCZ pathophysiology or results from medication effects.

aimsThis study investigated the relationship between peripheral GlcA levels and clinical characteristics in patients with SCZ and assess whether these associations persist independently of psychotropic medication effects to provide insight into the potential role of GlcA in the pathophysiology of SCZ.

methodsPlasma GlcA levels were analysed in 218 patients with SCZ, examining their association with clinical features. The correlation between GlcA levels and symptom severity, assessed using the Positive and Negative Syndrome Scale (PANSS), was analysed in 35 patients. In addition, multiple regression analysis was conducted to adjust for age and psychotropic medication effects.

resultsSignificant correlations were observed between GlcA levels and PANSS scores for negative symptoms, general psychopathology and total scores. After adjustment for age and psychotropic medications, significant correlations between GlcA levels and PANSS scores persisted for negative symptoms (adjusted β [95% CI], 13.926 [2.369, 25.483]) and general psychopathology (adjusted β [95% CI], 19.437 [3.884, 34.990]), while the total score was no longer significant (adjusted β [95% CI], 34.054 [-0.517, 68.626]).

conclusionsElevated GlcA levels in patients with SCZ are associated with specific symptom severity irrespective of the medication dose, suggesting a potential role of GlcA in SCZ pathophysiology.
