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

objectivesDepression is a complex mental disorder whose disease burden has become a major global public health issue. Sex is an important factor influencing susceptibility to depression, but the underlying mechanisms remain unclear. Previous studies have demonstrated a significant association between depression and acylcarnitine metabolism; however, systematic comparisons of acylcarnitine metabolic profiles between male and female patients with depression remain limited. This study aims to investigate sex differences in plasma acylcarnitine metabolic characteristics in first-episode, drug-naïve patients with depression, analyze the relationships between specific acylcarnitines and depression susceptibility and severity in different sexes, and explore the potential biological mechanisms underlying sex differences in depression from a metabolomics perspective.

methodsPlasma samples from first-episode, drug-naïve patients with depression and healthy controls collected in a clinical trial conducted between 2017 and 2020 were analyzed for carnitine levels. A total of 100 patients with first-episode, drug-naïve depression and 50 healthy controls were included. A two-step analytical strategy combining qualitative identification using ultrahigh-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF MS) and targeted quantification using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was applied to systematically detect plasma acylcarnitine metabolic profiles. Two-way analysis of variance (ANOVA) or the Scheirer-Ray-Hare test was used to examine the effects of depression diagnosis and sex differences on acylcarnitine levels. Multivariate linear regression analysis was further conducted to determine the associations between acylcarnitines, sex, depression susceptibility, and severity.

resultsA total of 33 acylcarnitines and free carnitine were detected in plasma. After preliminary analysis and screening, 8 acylcarnitines showed significant sex differences. Further multivariate linear regression analysis incorporating baseline characteristics revealed that acetylcarnitine C2:0 (

conclusionsThis study demonstrated significant sex differences in acylcarnitine metabolism in patients with first-episode depression. Among them, C2:0, C5:0, and C11:1 were key metabolites independently regulated by sex. C4:0, C11:1, C12:1-OH, and C13:1 were closely associated with depression susceptibility and anxiety severity. These findings suggest that dysregulation of mitochondrial fatty acid β-oxidation pathways may represent an important biological basis for sex differences in depression and provide new directions for precision classification and sex-specific diagnostic and therapeutic strategies for depression.
