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
Clear cell renal cell carcinoma (ccRCC) is a prevalent malignant tumor in the field of urology. The effect of cell heterogeneity on the prognosis and reaction to treatment of ccRCC in large populations is still unclear. By analyzing public single cell RNA-sequencing and bulk RNA-sequencing data with the Scissor algorithm, we have identified three distinct prognosis related cancer cell subtypes which play an indispensable role on tumor metastasis, immune response and proliferation respectively. Besides, regulatory T cells (Tregs) and matrix producing cancer associated fibroblasts (matCAFs) were also recognized as crucial cell subtypes in the tumor microenvironment (TME). Moreover, potential interactions between Scissor + cells and other cells in TME were investigated to uncover regulatory mechanisms via 'Cell Chat' and cell2location algorithm. It is interesting that the interferon gamma signaling pathway and p53 signaling pathway contribute to the Scissor + transition of Tregs and matCAFs. The distinct activated transcription factor patterns were uncovered as well as the essential ligand-receptor pairs in the interactions among different cell subtypes, such as CXCL12-CXCR4 and COL6A2-SDC4. Then, we developed a risk score signature consisting of 10 genes, utilizing a 101-combination machine learning computational framework, which showed promising results in predicting the prognosis of patients. Furthermore, our study revealed variations in immune cell infiltration and the expression of immune related factors within the tumor microenvironment between different risk score groups, as well as the different sensitivity to the immunotherapy. In the end, we suggested Rapamycin as the additional therapy for the advanced ccRCC. In conclusion, our study created a signature to provide opportunities for predicting prognosis and improving treatments of ccRCC.
