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
Recent studies have highlighted the relationship between ferroptosis in type II alveolar epithelial cell (ATII cell) and acute lung injury (ALI). Solute carrier family 38 member 1 (SLC38A1) is a member of the SLC38 gene family, expressed in the lung, and plays a crucial role in cellular processes. To explore the beneficial effects of SLC38A1 on ATII cell damage in Acute lung injury (ALI) from the perspectives of ferroptosis. Acute lung injury was established by intratracheal administration of lipopolysaccharide (LPS) in C57BL/6 mice for 24 hours. SLC38A1 overexpression was attained via adeno- associated virus serotype 6 (AAV6) transfection. Primary type II alveolar epithelial cell (ATII cell) were transfected with lentiviral vectors (LV) encoding SLC38A1, DMT1, shSLC38A1, shULK1, and shHSP90. Lung damage was assessed by TUNEL staining and pathological staining. Protein expression and interactions were assessed by western blotting and immunoprecipitation. SLC38A1 overexpression alleviated LPS-induced injury and inflammation by inhibiting oxidative stress and mitochondrial dysfunction in mice and ATII cells. Further results demonstrated that SLC38A1 overexpression inhibited ferroptosis, which was derived from promoting the degradation of Divalent Metal Transporter 1 (DMT1). SLC38A1 promoted the interactions among DMT1, HSP90, HSC70 and Lamp-2a, enhanced the lysosomal translocation of DMT1, and thereby intensified the chaperone-mediated autophagy (CMA) of DMT1. DMT1 overexpression accentuated LPS-induced lung injury and ATII cells injury, but the effects were relieved by SLC38A1 overexpression. SLC38A1 promotes DMT1 degradation through CMA, thereby inhibiting ferroptosis and improving lung injury. Consequently, we propose that SLC38A1 might serve as a potential therapeutic target and early diagnostic marker for ALI.
