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.

Abstract
Understanding the puff-by-puff delivery mechanisms of key components of heated tobacco products is critical to developing product designs. This study investigates the puff-by-puff release patterns of key components in Natural Smoke Cigarettes (NSCs), which are designed to deliver nicotine without combustion by reducing oxygen content, utilizing a 30-s puff interval, a 2-s puff duration, and a 55 mL puff volume to simulate realistic smoking conditions. By establishing models to analyze the variation of nicotine, glycerol, 1,2-propylene glycol (PG), and water in different functional sections of the cigarette under controlled smoking conditions. These sections include the tobacco, hollow, cooling, and filter sections, constituting the structure of NSCs. In addition, the model calculates the port-by-port release of the components in the flue gas aerosol and compares it with the measured value. The results showed that: The retention amount in the tobacco section showed a steep decline in the first three puffs, with an overall exponential decrease. The amounts in the other sections were consistent, increasing in the first two puffs and then stabilizing. The retention amount decreased linearly with each puff, with a similar pattern across sections. The release amount peaked at the fourth to fifth puffs and then stabilized. The retention amount in the tobacco section declined exponentially in the first three puffs. It peaked in the second to third puffs in other sections, then decreased with each subsequent puff. The retention amount in the tobacco section showed a significant decline in the first puff, stabilizing at around 4 mg. In other sections, it peaked at the first puff and then rapidly declined. These findings can inform the development of reduced-harm smoking products and contribute to a better understanding of the dynamics of smoke generation. Additionally, the study offers a reference for the puff-by-puff release stability of NSCs and the improvement of consumers' sensory quality.
