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
Prenatal stress (PNS) predisposes individuals to mental disorders later in life. Adolescence is a period of heightened brain plasticity and vulnerability, when many mental disorders emerge, yet pharmacological strategies remain largely underexplored. In adult PNS rats, lurasidone (LUR) has been shown to reduce PNS-induced risk; however, its effects following adolescent administration remain unclear. To investigate the long-lasting effects of PNS and their modulation following sub-chronic LUR adolescent treatment, a whole-genome expression analysis of the prefrontal cortex (PFC) of adult male PNS rats was performed. Twelve PNS and eleven control rats were randomly assigned to receive vehicle or LUR from postnatal day (PND) 35 to 49 and sacrificed at PND 50. Partek Genomics Suite and Ingenuity Pathway Analysis were used for differential expression and pathway analyses. Within the PFC, PNS induced an upregulation of pathways involved in environmental information processing and in immune system-related pathways, which was reduced after LUR, as observed by IL-8 signaling (z-scores before: 1.34 and after LUR: -2.65). In parallel, LUR administration itself modulated Inositol-related metabolic pathways. Overall, these findings suggest that LUR adolescent treatment may counteract some PNS-induced alterations, supporting adolescence as a critical window for early preventive strategies with translational relevance for stress-related neuropsychiatric disorders.
