Urinary lithogenic factors in urolithiasis patients with kidney disease and correlation with renal function.
Article in Frontiers in medicine, 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
Background: Patients with kidney disease have a high incidence of kidney stones, yet the specific mechanisms remain elusive. The purpose of this study was to explore the connection between urinary lithogenic factors and renal function. Methods: We retrospectively analyzed 150 patients with kidney disease -associated nephrolithiasis and 84 stone-forming patients with common nephrolithiasis. The renal disease group comprised 69 renal transplant recipients, 36 patients with CKD stages 1-2, and 45 patients with CKD stages 3-4. Urinary lithogenic factors and renal function indicators were compared and correlated. Results: Patients with kidney disease showed significantly higher calcium/creatinine and magnesium/creatinine ratios, and lower citrate/creatinine ratios and urinary uric acid levels, compared to those with common nephrolithiasis (all Conclusion: Patients with kidney disease had increased urinary calcium and magnesium excretion and decreased citrate levels compared to people with common nephrolithiasis. Kidney disease is associated with distinct alterations in urinary lithogenic factors, particularly hypocitraturia, with subtype-specific patterns that may guide targeted prevention strategies. These findings were based on a cross-sectional assessment using a single first-morning urine sample adjusted for urinary creatinine and should be validated with 24-h urine metabolic evaluation in future studies.
