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
objectiveTo explore the diagnostic and prognostic values of Sirtuin 6 (SIRT6) and Vanin-1 (VNN1) in peripheral blood monocytes of children with primary nephrotic syndrome (PNS) and their correlation with acute kidney injury (AKI).
methodsA retrospective analysis was conducted on 101 children (observation group) diagnosed with PNS and treated at the Shanxi University of Traditional Chinese Medicine Affiliated Hospital from December 2021 to December 2023. These children were categorized into two groups: the AKI group (n=35) and the non-AKI group (n=66), based on the presence of AKI. Additionally, 101 healthy children who underwent physical examinations during the same period served as the control group. Western blotting and RT-PCR were employed to measure the protein and mRNA levels of SIRT6 and VNN1 in monocytes across the three groups. The correlation between SIRT6 and VNN1 mRNA levels and clinical data, as well as kidney function indicators, was analyzed. The diagnostic value of SIRT6 and VNN1 mRNA levels for AKI in PNS was assessed using ROC curves. Multivariate logistic regression identified independent factors influencing AKI in PNS. The mRNA levels of SIRT6 and VNN1 were also compared before and after treatment in children with PNS.
resultsThe AKI group exhibited lower SIRT6 protein and mRNA levels, and higher VNN1 protein and mRNA levels in monocytes compared to the other groups (all P<0.05). Correlation analysis revealed that SIRT6 mRNA levels were positively correlated with serum creatinine (Scr), uric acid (UA), blood urea nitrogen (BUN), 24-hour urine protein (24h UP), cystatin C (Cys-C), and β2-microglobulin (β2-MG), but negatively correlated with albumin (ALB) and estimated glomerular filtration rate (eGFR) (all P<0.05). In contrast, VNN1 levels showed the opposite correlations (P<0.05). ROC curve analysis showed that the AUC for SIRT6 or VNN1 mRNA alone in diagnosing AKI was above 0.8, with a combined diagnostic AUC exceeding 0.9. Logistic regression indicated that eGFR, β2-MG, Cys-C, and the mRNA levels of SIRT6 and VNN1 were independent risk factors for AKI in PNS (all P<0.05). After treatment, SIRT6 mRNA levels significantly decreased, while VNN1 mRNA levels increased in children with PNS (both P<0.05).
conclusionSIRT6 and VNN1 are closely associated with AKI in children with PNS and may serve as valuable biomarkers for the diagnosis of AKI.
