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
objectiveRenal stone formation is closely linked to disturbances in urinary and serum mineral metabolism. Analysis of stone composition along with biochemical parameters is essential for understanding the pathogenesis of different stone types.
methodsA prospective observational study was conducted among 371 patients with renal stones. Stone composition was analyzed using Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy- Energy-Dispersive X-ray Spectroscopy techniques. Serum and 24-hour urinary biochemical parameters, including calcium, oxalate, citrate, phosphate, uric acid, pH, and urine volume, were evaluated. Statistical analysis was performed to assess differences and correlations between stone types and biochemical variables.
resultsThe mean age was 45.3 years, with male predominance and 39.9% recurrence. Calcium oxalate monohydrate was most common. Stone types differed significantly in urinary volume, pH, and mineral excretion. Uric acid stones showed low urine pH and volume, while calcium phosphate stones had higher calcium excretion and alkaline pH, with related serum differences.
conclusionRenal stone composition is strongly associated with specific urinary and serum biochemical abnormalities. Metabolic evaluation is crucial for identifying etiological factors and for guiding individualized preventive strategies in stone disease management.
