1 · What the graph read from it

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.

2 · The registry

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 a common and aggressive renal cancer with high mortality when metastasized. Cancer-associated fibroblasts (CAFs) are pivotal in ccRCC evolution; however, their significance in forecasting prognosis and guiding therapy is undetermined.

methodWe used Weighted Correlation Network Analysis to identify modules correlated with CAFs in bulk RNA-seq data. We also screened fibroblast marker genes in single-cell RNA-seq data and upregulated genes in TCGA tumor samples and defined genes identified in all three analyses as CAFs-related genes (CRGs). We extracted a CRG signature using Least Absolute Shrinkage and Selection Operator analysis and investigated its biological mechanisms by combining Gene Set Enrichment Analysis and the AUCell algorithm. The Tumor Immune Dysfunction and Exclusion algorithm and the IMvigor 210 dataset were employed to assess the signature's capability to predict immunotherapeutic responses. Additionally, we analyzed the relationship between the signature and the IC

resultsThe CRG signature was anchored on six genes: CERCAM, TMEM132A, TIMP1, P4HA3, FKBP10, and CEBPB. Kaplan-Meier analysis indicated that patients with high expression of the signature experienced poorer survival than those with low expression. Furthermore, immunotherapy was more effective in patients with low signature expression. In vitro assays revealed CERCAM silencing led to a substantial reduction in the proliferative and migratory capacities of ccRCC cell lines.

conclusionOur CRG signature holds promise in forecasting prognosis and guiding personalized treatment for patients with ccRCC.
