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
backgroundKidney stone disease (KSD) is a growing global health concern, with obesity (OB) as a major risk factor linked to metabolic dysfunction and chronic inflammation. Although the common method for evaluating OB is body mass index (BMI), it is not specific enough when it comes to reflecting visceral fat. The perirenal fat thickness (PFT) might present better predictive capabilities. The goal of this research was to assess the clinical usefulness of PFT in the diagnosis of KSD and to clarify the molecular mechanisms connecting OB to KSD.
methodsAnalysis was carried out on a retrospective cohort of 413 patients (265 having KSD and 148 controls). Abdominal computed tomography was used to measure PFT. Three machine-learning methods, weighted gene co-expression network analysis, and differential expression analysis were used to evaluate gene expression data for key gene identification. Internal and external datasets were used to develop and validate a diagnostic nomogram. Also, pathway enrichment analysis was carried out.
resultsKSD patients exhibited greater PFT versus controls, with significantly enhanced diagnostic accuracy compared to BMI. Multivariate analysis confirmed PFT as an independent predictor of KSD (OR = 1.20, P < 0.001). Eight genes that are differentially expressed in relation to OB were identified, among which FAM20A and DHRS9 were found to be central hub genes. The nomogram exhibited a high level of predictive accuracy. Analysis of enrichment pointed to the IL-6/JAK/STAT3 and TNF-α/NF-κB signaling pathways in the connection between perirenal fat and KSD.
conclusionsPFT serves as a practical and dependable marker for the risk of KSD. It is superior to BMI and can be conveniently incorporated into routine clinical practice. Stone formation may be linked to perirenal fat by FAM20A and DHRS9 via inflammatory pathways, which provides potential targets for the management of OB-related KSD.
