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
Postoperative recurrence for papillary renal cell carcinoma (PRCC) remains a tough problem in clinic. Previous studies have shown that general control nonderepressible kinase 2 (GCN2) was critically involved in tumour development. However, its function and clinical significance in renal cancer remain unknown. In this study, we investigated the role of GCN2 in PRCC. GCN2 silencing suppressed the viability and proliferation, promoted apoptosis of renal cancer cells. We found that the protein level of GCN2 was increased in PRCC tissues. Immunohistochemistry was performed in 84 patients with PRCC to explore the association of GCN2 level with clinical significance. High GCN2 protein level was observed to be significantly correlated with adverse clinicopathological parameters, such as larger tumor size, higher TNM stage, higher Fuhurman Grade, and lymph node metastasis. We evaluated patient outcomes according to various clinical parameters as well as GCN2 expression by Kaplan-Meier curves. Multivariate analysis revealed that GCN2 overexpression can be a predictive factor correlated with reduced OS and PFS of postoperative PRCC patients. Collectively, GCN2 is potentially to play crucial roles in PRCC progression, and its overexpression may be used to predict poor prognosis and promising therapeutic strategy for PRCC patients.
