An Efficient Solid Phase Extraction Method for Purification and Analysis of Compound-Specific Plant Sugar Stable Hydrogen Isotope Values.
Article in Rapid communications in mass spectrometry : RCM, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
rationaleThe stable hydrogen isotope composition (δ
methodsWe evaluated methods that use acetylation of soluble carbohydrate plant extracts to aid in purification as well as isotopic analysis of plant sugars such as sucrose. Extracts were obtained using either hot water or hot 80% ethanol. Acetylated extracts were then purified using an established liquid-liquid separation (LL) method or a new solid phase extraction (SPE) method that we developed. We also evaluated glucose produced from starch after enzymatic digestion. Method performance was evaluated based on quantified yields and the impact on measured δ
resultsAcetylated sucrose and starch-derived glucose were sufficiently resolved for gas chromatography in all cases. No isotopic biasing was detected for any method. Acetylated sucrose yields differed among methods, with 80% ethanol resulting in approximately threefold higher extraction yield compared to water, and SPE giving smaller but still sufficient yields compared to LL. Sample throughput was doubled with the SPE method compared to the LL method, which allows for larger batch sizes compared to LL.
conclusionsWe developed an efficient method to analyze compound-specific plant carbohydrate δ
