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
Background: Independent of age, sex, and body composition, individuals of African American race and individuals with high muscle mass have elevated serum creatinine (sCr) levels on average that may result in overestimation of chronic kidney disease (CKD). We present a misdiagnosed case of CKD based on sCr levels, illustrating the utility of cystatin C (CysC) confirmation testing to answer the question: Can confirmation screening of kidney function with CysC in African American patients and patients with high muscle mass reduce the misdiagnosis of CKD? Case Presentation: A 35-year-old African American man with a history of well-controlled HIV was found to have consistently elevated creatinine (Cr). We diagnosed CKD stage 3A based on the estimated glomerular filtration rate (eGFR). Further evaluation showed isolated elevation of sCr with unremarkable urinalysis and other laboratory tests. sCr elevation predated diagnosis and HIV treatment. A CysC-based eGFR (eGFR Conclusions: The 2009 CKD Epidemiology Collaboration calculation of eGFR based on sCr concentration uses age, sex, and race, with an updated recommendation in 2021 to exclude race. Both equations are less accurate in African American patients, individuals taking medications that interfere with sCr secretion and assay, and patients taking creatine supplements or high protein intake. These clinical scenarios decrease sCr-based eGFR (eGFR
