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
background and purposeMitochondrial autophagy, also referred to as mitophagy, clears damaged mitochondria and has dual functions in disease development and liver homeostasis in response to liver pathologies. Mesenchymal stem/stromal cells (MSCs) are most commonly used to treat liver failure because they are easy to obtain and present no ethical problems. However, the molecular mechanisms by which MSCs promote liver failure progression are not fully understood. This study explored the distinct mitophagy states in hepatocytes and macrophages during MSCs therapy. EXPERIMENTAL APPROACH: To investigate tissue-specific mitophagy in acute liver failure (ALF), we generated a single-cell transcriptome (scRNA-seq) atlas of liver tissue from healthy mice, ALF mice and human umbilical cord mesenchymal stem/stromal cell (hUC-MSC)-transplanted mice. KEY
resultsThe data revealed the complex cellular landscape of liver tissue during ALF progression, revealing alterations in metabolic fluxes and mitophagy activation. Through the intersection of single-cell sequencing data with mitophagy-related genes (MRGs), a total of 24 differentially expressed MRGs were identified. Gene Ontology (GO) analysis further revealed that the ubiquitinating enzyme Arih1 was significantly upregulated after MSC transplantation, whereas the mitophagy genes Bnip3L/NIX and Beciln1 were significantly downregulated in mononuclear phagocytes(MPs). CONCLUSIONS AND IMPLICATIONS: Our research demonstrated that during the development of ALF, mitophagy within hepatocytes is suppressed, whereas in MPs, mitophagy is excessively activated. MSCs are capable of alleviating disease progression by modulating the distinct mitophagy states of cells, providing an important resource for investigating mitophagy regulation in hepatic homeostasis and disease development.
