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

backgroundExecutive dysfunction is common and impairing in youth bipolar disorder (BD), and oxidative stress (OS) and brain-derived neurotrophic factor (BDNF) have been implicated in executive deficits of adult BD. This study aimed to determine the association between OS and executive dysfunction in BD adolescents and the influence of BDNF on this association.

methodsSerum levels of lipid hydroperoxides (LPH) and 4-hydroxy-2-nonenal (4-HNE) and BDNF levels were measured in 29 BD and 25 control adolescents. The intra-extra-dimensional (IED) set-shifting task assessed executive function. Lower IED scores indicated better performance. High and low BDNF subgroups were defined by median split.

resultsIED Z-scores were impaired in the BD group compared to controls, whereas biomarker levels were not significantly different between groups. LPH-BDNF correlations were significantly different between BD and controls (Z = 2.046, p = 0.041). In high BDNF BD subjects, LPH was significantly positively correlated with IED completed stage trials (ρ = 0.755, p = 0.001) and pre-extra-dimensional shift errors (ρ = 0.588, p = 0.017). Correlations were opposite in controls. In a linear model, LPH, BDNF, and the LPH-BDNF interaction each significantly explained variance of IED total trials (adjusted) (model r

conclusionsThere is a negative association between LPH and executive function in BD adolescents, which may be modulated by BDNF. LPH and BDNF may be useful biomarkers of executive function in BD. These findings highlight the importance of examining multiple peripheral biomarkers in relation to cognitive functions in BD adolescents. Future studies should explore these factors in longitudinal designs to determine the directionality of observed associations.
