Shedding Light on the Past: Temporal Classification of Zoological Specimens from Museum Collections with Portable NIR Sensors and Multivariate Error Modeling.
Article in Analytical chemistry, 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
Museum scientific collections preserve invaluable biological archives that provide insights into historical biodiversity and environmental change. Determining the age of specimens often relies on destructive, labor-intensive, and costly methods, limiting their use on rare or valuable materials. In this study, we present a fully nondestructive and rapid approach for classifying the temporal origin of zoological skeletal specimens using portable near-infrared spectroscopy combined with an advanced chemometric framework, exemplified by red squirrel (
