Hyperuricemia accelerates renal dysfunction due to hypertensive nephrosclerosis: the TAMA MED Project-CKD.
Article in BMC nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundNephrosclerosis has become an increasingly common underlying cause of renal replacement therapy worldwide. Hypertension is the primary cause of nephrosclerosis; however, other complex factors are believed to contribute to its onset and progression. In this study, we aimed to investigate whether hyperuricemia is a risk factor for the onset of chronic kidney disease and for progression of renal dysfunction. Additionally, we sought to determine whether the coexistence of hypertension and hyperuricemia exacerbates these risks.
methodsA follow-up survey was conducted among 11,043 individuals aged 40–74 years in Tama City who underwent specific health checkups in 2016 and continued to receive health checkups for up to 6 years. We investigated the effects of hyperuricemia and hypertension at baseline on the subsequent development of proteinuria and decline in renal function.
resultsElevated uric acid levels in both men and women were not associated with the onset of proteinuria; however, they were identified as risk factors for estimated glomerular filtration rate (eGFR) falling below 60 mL/min/1.73 m² during follow-up, with cutoff values of 5.4 mg/dL for men and 4.6 mg/dL for women. Even in the presence of hypertension, elevated uric acid levels further increased the risk of eGFR falling below 60 mL/min/1.73 m². Additionally, hyperuricemia was an associated factor for a > 1.5-fold increase in serum creatinine levels during follow-up, with cutoff values of 7.1 mg/dL for men and 5.2 mg/dL for women. The coexistence of hyperuricemia and hypertension further amplified the risk of a > 1.5-fold increase in serum creatinine levels.
conclusionThe combination of hypertension and hyperuricemia appears to increase the risk of renal function deterioration due to nephrosclerosis. CLINICAL TRIAL NUMBER: Not applicable.
