Berry e-liquid flavour toxicities are not equal on an alveolar-capillary barrier cell model according to two exposure methods.
Article in Frontiers in toxicology, 2026. 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
E-cigarettes are often presented as a smoking cessation tool, less harmful than tobacco and are now a regular feature of everyday life. However, the fruity and sweet flavours are attractive to teenagers who can use them recreationnaly. The main risk of this phenomenon is becoming trapped in nicotine addiction. Although e-liquids, which combine nicotine, humectants and flavouring agents, seem to affect the pulmonary system and in particular the alveolar-capillary barrier (ACB), data on nicotine-free e-liquids remain scarce. The aim of this work is to study the toxicity of nicotine-free e-liquids/aerosols flavoured with berries (Strawberry, Raspberry, Blackberry, Blueberry) using two exposure methods. First, we validated an
