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
Ferroptosis, a form of regulated cell death triggered by lipid peroxidation, is implicated in various degenerative diseases and bone regeneration. In this study, we hypothesized that the ferroptosis inhibitors Liproxstatin-1 (Lip-1) and Coenzyme Q10 (CoQ10) play a dual role in protecting cells against ferroptotic damage and promoting osteogenic differentiation in MC3T3-E1 cells. Erastin-induced ferroptosis significantly reduced cell viability and increased lipid peroxidation, as evidenced by BODIPY™ 581/591 C11 staining. Both Lip-1 and CoQ10 decreased lipid peroxidation and restored cell viability, particularly at early treatment points. Post-treatment recovery experiments showed that both agents reversed erastin-induced damage, with Lip-1 having a stronger and more sustained effect. ALP activity assays on day 14 revealed dose-dependent increases with Lip-1 and moderate stimulation with CoQ10, indicating additional osteoinductive properties. Moreover, cell density affected sensitivity to lipid peroxidation, with higher cell densities providing protection through antioxidant pooling. These results highlight CoQ10 and Lip-1 as promising candidates for bone tissue engineering, as they offer protection against ferroptosis and promote osteoblast differentiation. Overall, this study emphasizes the therapeutic potential of ferroptosis modulators for bone regeneration.
