Breath ammonia test for chronic kidney disease screening: impact of fasting on diagnostic accuracy.
Article in Clinical kidney journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Chronic kidney disease (CKD) is a global health concern and early detection is crucial for preventing progression. Current screening methods are inconvenient and resource intensive. Breath ammonia has been proposed as a non-invasive biomarker for renal dysfunction but its diagnostic accuracy and the impact of fasting remain unclear. This study aimed to validate the breath ammonia test for CKD screening and assess the effect of fasting on its diagnostic performance. Methods: This prospective study included 244 participants: a derivation cohort ( Results: The average age of the participants was 60.7 years, with males comprising 51% of the cohort. Breath ammonia levels significantly correlated with serum creatinine ( Conclusions: The breath ammonia test is a promising non-invasive CKD screening tool. Standardizing pretest fasting may further improve its diagnostic accuracy.
