The dating of leather bindings using ER-FTIR spectroscopy and machine learning.
Article in Scientific reports, 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
Libraries and archives hold large collections of medieval manuscripts that are of cultural importance to the regions they serve. These collections are often highly studied for their written material as a snapshot of how life was at the time of writing. By studying that, codicologists can estimate a moderately accurate date for the objects, but it requires significant time, expertise, and effort to achieve these dates. Limitations regarding sample collection and preparation prevent large scale and robust scientific investigation of these culturally significant collections. Recent advancements in the scientific community around non-destructive and non-invasive analysis have helped open the door to study these collections. This study attempts to utilize External Reflectance Fourier Transform Infrared (ER-FTIR) spectroscopy as a tool for molecular decay (MD) dating. By working closely with codicologists and conservators, it is possible to build an MD dating tool by looking at the chemical differences in leather as it ages. With an estimated uncertainty of ± 66 years, this study aims to prove that it is possible to have an accurate dating tool that is fast, easy to interpret, and non-destructive/non-invasive to cultural heritage collections.
