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
backgroundIn recent years, there has been a rapid increase in disposable electronic cigarette (e-cigarette) use. Several countries have banned or are considering banning disposable e-cigarettes, which might affect adults who use disposable e-cigarettes for harm reduction. Understanding patterns of disposable versus non-disposable e-cigarette use among adults who currently use e-cigarettes is essential to inform possible regulations and policy. This study explored factors associated with disposable versus non-disposable e-cigarette use among adults currently using e-cigarettes in the U.S. and Israel.
methodA cross-sectional online survey was conducted (October-December 2021) among 410 U.S. and Israeli adults aged 18-45 years (mean age 30.8 ± 7.6) who reported past 30-day e-cigarette use (62.9% of whom used non-disposables). A multivariate logistic regression assessed factors associated with disposable versus non-disposable e-cigarette use, stratified by country.
resultIn Israel, a greater perceived harm of e-cigarettes (aOR = 1.45, 95%CI: 1.20-1.76), cannabis/cannabinoid-containing e-liquid use ( aOR 0.36, 95%CI: 0.19-0.69) and purchasing from 'regular' shops (aOR = 6.30, 95%CI: 2.25-17.67) or 'specialty' shops (aOR = 3.71, 95%CI: 1.21-11.34) (compared to 'online' shops) were associated with disposable e-cigarette use. In the U.S., factors associated with disposable e-cigarette use included ever using other tobacco/nicotine products (aOR = 7.51, 95%CI: 1.49-37.87), sweet flavor preference (aOR = 4.42, 95%CI: 1.64-11.94), cannabis/cannabinoid-containing e-liquid use (aOR = 0.33, 95% CI: 0.13-0.82), and being 26-35 years old (vs. 36-45) (aOR = 0.36, 95% CI: 0.13-0.98).
conclusionsU.S. and Israeli adults who use disposable versus non-disposable e-cigarettes differ, highlighting the importance of public health strategies tailored to the unique needs of each country. The high levels of cannabis or cannabinoid-containing e-liquid use among participants who use non-disposable e-cigarettes suggest the need for stricter regulation and enforcement of non-disposable devices and e-liquids in both countries. Findings also suggest that banning sweet flavored e-cigarettes will support the effort in reduction of disposable e-cigarette use in the U.S.
