E-cigarette flavor and device preferences among US pregnant women who smoke: A latent class analysis.
Article in Tobacco prevention & cessation, 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
introductionLittle is known about e-cigarette device and flavor preferences among pregnant women. The purpose of this study was to identify classes of e-cigarette use based on device and flavor preferences among pregnant women who report dual use of e-cigarettes and cigarettes.
methodsA sample of pregnant women (n=118), aged 18-40 years, living in the US, with dual cigarette and e-cigarette use, completed a cross-sectional online survey. Participants reported e-cigarette characteristics including past 30-day e-cigarette device (cartridge-based, JUUL, tank, and disposable) and flavor use (tobacco, mint, spice, sweet, alcohol, combined), and use of e-cigarettes containing delta-9-tetrahydrocannabinol (THC) in pregnancy. We used latent class analysis to classify subgroups based on e-cigarette preferences in pregnancy and examined the association of sociodemographic variables and cigarette smoking frequency with class membership.
resultsWe found four distinct classes of e-cigarette preferences: Class 1) tobacco, mint, and sweet JUUL (50.4%); Class 2) THC, all flavors, and JUUL (28.1%); Class 3) THC, all flavors, and all device (12.4%); and Class 4) THC, tobacco, mint, sweet, and tank device (9.1%). Pregnant women who smoked ≥11 cigarettes per day, compared to those who smoked 1-10 per day, were 5.22 (95% CI: 1.85-14.70) and 5.55 times (95% CI: 1.49-20.61) as likely to use THC, all flavors, and JUUL and all devices, respectively, compared with those who used tobacco, mint, and sweet flavors with JUUL.
conclusionsPregnant dual users of cigarettes and e-cigarettes are a heterogenous group. Device and flavor differences should be considered when developing targeted messaging campaigns and prevention strategies.
