Plant Volatile Organic Compound Collection: Superior Odor-Trapping Efficiency of Mesoporous Carbons over Porous Polymers.
Article in ACS omega, 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
Dynamic headspace collection (DHC) using adsorbent matrices is a standard technique for capturing representative profiles of plant volatile organic compounds (VOCs). While solvent desorption (SD) of adsorbent-trapped VOCs facilitates downstream analysis, the optimal adsorbent selection for SD-DHC remains underexplored. This study systematically evaluated 6 carbon-based matrices, 3 commonly used porous polymers, and silica gel for SD-DHC applications. Adsorbent performance was assessed through adsorption capacity measurements using 34 synthetic VOC standards, breakthrough tests with two traps connected in series, residual analysis, and validation of efficiency by sampling VOCs from cut cabbage pieces and herbivore-damaged cotton seedlings. Results demonstrated that Carboxen 1000, Carbopack X, and Carbopack Z exhibited superior overall VOC collection capacity, minimal breakthrough, and low residual levels consistent with their large surface areas and optimized mesoporous structures. Validation tests confirmed the effectiveness of these adsorbents in capturing diverse plant VOC profiles, indicating significant application potential for complex plant volatile sampling.
