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
backgroundTumor-associated macrophages (TAMs) are linked with tumor progression in clear cell renal cell carcinoma (ccRCC), but the role of perinephric adipose tissue macrophages (PATMs) in ccRCC has not been elucidated. The aim of this study was to illustrate the association between PATMs and the prognosis of localized ccRCC.
methodsA total of 135 consecutive patients who underwent radical or partial nephrectomy, with histopathologically confirmed ccRCC, from May 2018 to September 2019, were retrospectively enrolled. Macrophages in perinephric adipose tissue were detected by CD68 immunohistochemical staining. The density of PATMs was evaluated in relation to clinicopathological parameters and disease-free survival (DFS).
resultsWe divided the patients into two groups according to the density of PATMs, 51 (37.8%) were identified as “PATMs-high”, and 84 (62.2%) were identified as “PATMs-low”. Patients with high PATMs density significantly correlated with male gender (P = 0.003), advanced T stage (P < 0.001), higher rate of perinephric fat invasion (P = 0.006), more severe perinephric stranding (P < 0.001), and higher MAP score (P = 0.014). Kaplan-Meier analysis demonstrated that high density of PATMs was significantly correlated with poor DFS (P < 0.001). In multivariate Cox analysis, tumor size (HR: 1.241, 95% CI: 1.045–1.474, P = 0.014), MAP score (HR: 3.742, 95% CI: 1.698–8.248, P = 0.001), and PATMs density (HR: 3.011, 95% CI: 1.469–6.170, P = 0.003) were independent predictors of DFS in ccRCC.
conclusionsPATM may serve as a novel prognostic predictor and potential therapeutic target in patients with ccRCC.
