Stability Evaluation Method and Application of Puff-by-Puff Release of Aerosol Constituents in Heated Tobacco Materials and Products.
Article in ACS omega, 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
Puff-by-puff release stability is critical for heated tobacco product (HTP) quality and user experience, yet existing methods lack dynamic puff-by-puff evaluation. Here, we develop a novel stability index (SI) using the "modulus of the sum vector of two evaluation dimensions" algorithm to quantify puff-by-puff release consistency and interpuff variability. In addition, the algorithm has been validated through practical product applications. Compared with traditional methods, SI significantly enhances the differentiation and accuracy of stability evaluation. Under a 10% relative deviation in the release amount measurement, the deviation of the stability index (SI) is maintained at 10.6%, demonstrating precision. The SI is applicable to reconstituted tobacco sheets, HTP sticks, and final products, enabling quantitative stability assessment. As a key screening tool, it streamlines HTPs development by identifying inconsistent formulations early.
