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
Head and neck squamous cell carcinoma (HNSCC) has a high rate of metastasis and recurrence, and poses a considerable threat to patient survival. Autophagy, an intracellular degradation pathway, plays a crucial role in tumor progression; however, the underlying mechanisms of action remain unclear. This study aimed to explore the role of the ACSS2-TFEB axis in the regulation of autophagy and its impact on HNSCC cell proliferation, migration, invasion, and lysosomal function. HNSCC tumor tissues and cell lines were analyzed for ACSS2 protein expression. The effects of the ACSS2 knockdown on cell proliferation, migration, invasion, and autophagic flux were also assessed. The interaction between ACSS2 and transcription factor EB (TFEB) and its influence on lysosomal function were also examined. In this study, we found that ACSS2 protein expression was significantly upregulated and correlated with metastasis and poor prognosis. ACSS2 knockdown inhibited the proliferation, migration, and invasion of HNSCC cells, and disrupted autophagy flux, primarily by impairing lysosomal function. Additionally, ACSS2 was found to sustain autophagic flux through TFEB activation, a key regulator of the autophagy-lysosome pathway. TFEB activation promotes lysosomal function and autophagic flux, thereby facilitating tumor cell growth and metastasis. This study elucidated the molecular mechanism by which ACSS2 enhances HNSCC cell proliferation and invasion via TFEB activation. The ACSS2-TFEB axis is a potential therapeutic target for HNSCC and provides a foundation for the development of targeted therapies.
