Comprehensive assessment and prediction of calcium-phosphorus precipitation in parenteral nutrition using advanced monitoring and data mining techniques.
Article in Frontiers in nutrition, 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: Calcium-phosphate precipitation poses a significant risk in parenteral nutrition. Existing compatibility studies are predominantly qualitative with inconsistent safety thresholds. This study aimed to develop a quantitative predictive framework to overcome these limitations. Methods: A novel high-sensitivity real-time precipitation monitoring device was developed. The compatibility of six calcium-phosphorus formulation pairs was systematically evaluated under clinically relevant conditions using a factorial design, generating 15,342 experimental observations. Four data mining models-C5.1, CHAID, Support Vector Machine, and Artificial Neural Network-were constructed and compared. Results: Analysis established distinct compatibility profiles. Precipitation was exclusive to inorganic phosphate combinations, specifically calcium chloride or calcium gluconate with potassium dihydrogen phosphate, while organic phosphate formulations remained stable within the tested concentration ranges. Six significant predictors were identified: calcium concentration, phosphorus concentration, pH, and temperature as risk factors, alongside 18AA-II and 18AA-V as protective factors. The C5.1 algorithm demonstrated optimal performance, achieving 98.5% predictive accuracy. External validation using 100 independent clinical samples confirmed robust performance (95% accuracy), facilitating the creation of a web-based clinical decision platform. Conclusions: This study provides a systematic quantitative evaluation of clinically used calcium-phosphorus combinations under clinically relevant conditions. A data-driven framework that links experimental evidence with clinical decision-making and contributes to improved parenteral nutrition safety is established by integrating real-time precipitation monitoring, a large experimental dataset, predictive modeling, and external validation.
