Salivary BCAA, Glutamate, Glutamine and Urea as Potential Indicators of Nitrogen Metabolism Imbalance in Breast Cancer.
Article in Current issues in molecular biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Nitrogen metabolism in the human body is in a strictly balanced state, which is disturbed in pathologies, including breast cancer. The state of nitrogen balance can be judged by the content of urea and the amount of branched-chain amino acids (BCAAs) (Val, Leu, and Ile), glutamine (Gln), and glutamate (Glu). The study involved 1438 people, including patients with breast cancer (n = 543), fibroadenomas (n = 597), and healthy controls (n = 298). Saliva samples were collected from all patients before treatment, and urea levels were determined in all 1438 samples. Salivary levels of BCAAs, Gln, and Glu were determined in 116 patients with breast cancer, 24 with fibroadenomas, and 25 healthy volunteers. An increase in the concentration of urea in saliva was shown in breast cancer, most pronounced in luminal molecular biological subtypes: luminal A 10.46 [7.69; 12.62] mmol/L (
