Puffing topography: a tool to evaluate vaping behavior and exposure risks.
Review in Inhalation toxicology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The ever-changing popularity of electronic nicotine delivery systems (ENDS) among both youth and adults in the United States has been influential in shaping users' perceptions and behaviors. This behavior driven ENDS usage is described as puffing topography (PT) which includes user's puff duration, flow rate, intra puff interval, the volume of e-liquid used and total number of puffs per session. These metrics are not only useful for characterizing individual vaping behaviors but are also critical for assessing the extent of exposure to potentially harmful substances such as nicotine, volatile organic compounds (VOCs), and particulate matter emitted during use. Previous studies have indicated that puff volume and flow rate are distinct but related parameters that determine exposure to hazardous emissions among users and bystanders. However, current evidence suggests that vaping behavior is also influenced by the age at which users first encounter ENDS, the strength of the nicotine present, and whether users develop circadian patterns of ENDS usage. This review article, which is a part of the Special Issue Science Education and Research on Vaping and Interventions for Community Engagement summarizes the critical aspects of PT and explores how various factors including lifestyle, gender, e-liquid composition (such as flavor and nicotine concentration), and device parameters can influence exposure risks. The standardization of puffing topography as a tool to evaluate vaping behavior and exposure risks to toxic emissions could be instrumental in developing consensus standards for ENDS and protecting public health.
