Neural Networks for Quantifying Laboratory Confocal Micro X-ray Fluorescence Measurements.
Article in Analytical chemistry, 2025. 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 quantification of confocal micro X-ray fluorescence spectroscopy (CMXRF) data obtained with polychromatic excitation in a laboratory setup is challenging. Complex dependencies, an elaborate setup calibration and nontrivial data evaluation makes it a time-consuming and intricate task. In this work we introduce the first application of a neural network for the quantification of homogeneous bulk samples, which significantly simplifies the evaluation and effectively eliminates the need for human input. The training of the neural network is performed on simulated data. For this, a simulation routine for CMXRF data of homogeneous bulk samples is introduced. The neural network is trained to simultaneously quantify the elemental concentrations of 53 elements, the density of the sample and the surface position directly from depth profiling measurements. As a result, the CMXRF evaluation is substantially simplified and the potential of the used neural network for feature extraction and prediction is demonstrated.
