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
introductionThis study examined how e-cigarette purchasing locations are associated with tobacco use pattern and socio-demographics of e-cigarette users in the United States.
methodsBased on a nationally representative sample of adult e-cigarette users, we assessed their purchasing locations (internet, vape shops, tobacconists, brick-and-mortar retailers, temporary sales, somewhere else including foreign country) and associations with individual demographics, frequencies of e-cigarette and cigarette use, e-cigarette product type of choice, state-level cigarette, and e-cigarette taxes.
resultsIn 2023, the most popular purchasing locations reported by adult e-cigarette users were: vape shops (65.5%), general purpose brick-and-mortar stores (43.4%), and internet (18.6%). Dual use of e-cigarettes and cigarettes was associated with higher odds (odds ratio = 5.3-5.5, p < .05) of buying from tobacconists. Older (odds ratio = 3.0-5.2, p < .01) and Hispanic (odds ratio = 2.85, p < .01) adults were more likely to make online purchases. Compared with exclusive disposable users, exclusive tank system users were more likely to buy online (odds ratio = 6.22, p < .001) or from vape shops (odds ratio = 2.61, p < .01), and exclusive rechargeable (pod/cartridge) users were less likely to buy from vape shops (odds ratio = 0.29, p < .001). One additional dollar tax per 1 mg of e-liquid volume was associated with higher odds of buying from somewhere else or foreign countries (odds ratio = 1.88, p < .01).
conclusionsE-cigarette use frequency, dual use status of e-cigarettes and cigarettes, age, race/ethnicity, and e-cigarette product type of choice are related to U.S. adults' e-cigarette purchasing locations.
