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
backgroundClear cell renal cell carcinoma (ccRCC) is the predominant subtype of renal cancer, with a poor prognosis driven by therapy resistance and a propensity for recurrence. Tumor microenvironment (TME)-associated fibrosis accelerates disease progression by fostering immune evasion. Neuropilin-1 (NRP1), a key mediator in fibrotic signaling and cancer biology, has been implicated in these processes. However, the genetic correlation between fibrogenesis and ccRCC remains largely unexplored, necessitating a focused analysis of fibrogenesis-related genes (FRGs) to identify novel prognostic markers and therapeutic strategies.
methodsThis study utilized an integrative bioinformatics framework to identify prognosis-associated fibrogenesis-related genes (pFRGs) and applied non-negative matrix factorization (NMF) to stratify ccRCC patients based on fibrotic signatures. A machine learning-derived prognostic model was developed to categorize patients into high-risk and low-risk groups, with tumor microenvironment (TME) features analyzed across these subgroups. The pro-tumorigenic role of NRP1 via the TGF-β/SMAD signaling pathway was validated in vitro and in vivo.
resultsTwelve pFRGs were identified, with elevated expression correlating with reduced survival. NMF revealed two ccRCC subtypes with different fibrotic and immune profiles. The high-fibrosis subtype showed worse survival and a pro-tumorigenic TME. The risk model demonstrated robust predictive performance (AUCs: 0.738, 0.731, 0.711 for 1-, 2-, and 3-year survival). High-risk patients, marked by immune dysfunction, exhibited worse survival but greater immunotherapy sensitivity. Among the pFRGs, NRP1 was upregulated in ccRCC, and paradoxically associated with favorable prognosis in TCGA, primarily due to stromal enrichment. In vitro and in vivo experiments confirmed that NRP1 promotes ccRCC proliferation, migration, and invasion by enhancing TGF-β/SMAD-driven epithelial-mesenchymal transition (EMT).
conclusionFibrosis is a critical driver of ccRCC progression, linking fibrogenesis-related genes to poor prognosis, immune suppression, and tumor aggressiveness. NRP1 was identified as a central regulator of fibrosis-induced tumor progression through the TGF-β/SMAD signaling pathway. Combining NRP1 inhibition with anti-fibrotic therapies presents a potential strategy for enhancing therapeutic outcomes in ccRCC.
