A Validated LC-MS/MS Method for Quantifying Phenolic Acids, Lignans, and Enterolignans from Human Fecal Samples.
Article in ACS nutrition science, 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
The human gut is home to numerous small molecules that impact health. Three prominent classes of molecules in this environment are phenolic acids, lignans, and enterolignans, which have been linked to anti-inflammatory and antioxidant effects as well as protection from cancer, cardiovascular disease, and neurodegeneration. The abundance of these molecules in the intestine as well as their biological significance motivated the development and validation of the LC-MS/MS method reported herein, which provides a simple, robust, and high-throughput approach to simultaneously quantify a 22-membered panel of phenolic acids, lignans, and enterolignans in human fecal samples. Facile sample preparation and a short analytical time (5 min per sample, compared to similar methods that range from 7.8-28 min) allow for high throughput. A 16-fold increase in sensitivity allows for quantitation of lignans that are often not detected via existing methods.
