1 · What the graph read from it

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.

2 · The registry

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

A proof-of-concept approach is introduced that uses silver nanoparticles modified with Epimedium plant extract (EE-AgNPs) for BPA detection. The EE-AgNPs aggregate in the presence of BPA, demonstrating a measurable color change. This color change is monitored via a smartphone, enabling the prompt on-site determination of BPA. The sensor exhibited a linear response within the range 0.1-50 µM and a limit of detection (LOD) of 22 nM, which is below the thresholds set by the United States Food and Drug Administration, the National Health and Family Planning Commission of China, and European Union's specific migration limits, rendering it appropriate for the testing of polluted water and biological samples. Moreover, the study provides promising recoveries for BPA in water and biological specimens. The assimilation of the colorimetric system with smartphone offers a potential, cost-effective, and efficient option to traditional chromatographic approaches, especially for the initial evaluation of biological and polluted water samples.
