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

backgroundATP-binding cassette (ABC) transporters regulate xenobiotic efflux, oxidative stress responses, and blood-brain barrier (BBB) homeostasis. Dysregulation of transporters such as ABCC1, ABCB1, and ABCA2 has been linked to neuropsychiatric disorders, yet their expression patterns in schizophrenia and their modulation by antipsychotic treatment remain unclear. This study investigated longitudinal changes in the expression of these genes in schizophrenia patients before and after antipsychotic therapy, compared with healthy controls.

methodsSixty individuals with schizophrenia and sixty matched healthy controls were included. Serum samples were obtained from patients during the acute pre-treatment phase and after clinical improvement following antipsychotic therapy. Gene expression of ABCC1, ABCB1, and ABCA2 was measured by RT-qPCR (normalized to ACTB). Log2 fold-change (log2FC) values relative to controls were calculated. Group differences were assessed with Mann-Whitney U and Wilcoxon signed-rank tests, and associations with clinical severity were analyzed using correlations with Positive and Negative Syndrome Scale (PANSS) scores.

resultsIn the acute phase, ABCC1 and ABCB1 expression were significantly downregulated in schizophrenia compared with controls (both

conclusionsThese findings demonstrate distinct, gene-specific alterations in ABC transporter expression in schizophrenia. ABCC1 and ABCB1 appear suppressed during acute illness and partially restored with antipsychotic therapy, while ABCA2 shows a strong treatment-related upregulation. ABC transporter expression-particularly ABCB1-may provide preliminary molecular insight into treatment-related variability, although biomarker utility cannot be established from the present data. Longitudinal pharmacogenomic studies are needed to clarify their clinical relevance.
