1 · What the graph read from it

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.

2 · The registry

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

aimsLittle is known about features of e-cigarettes (EC) that facilitate or hinder the switch from smoking to vaping. We tested eight brands of EC to determine how nicotine delivery and other product characteristics influence user's initial reactions.

methodsFifteen vapers tested each product after overnight abstinence from both smoking and vaping. At each session, participant's vaped ad lib for 5 min. Blood samples were taken at baseline and at 2, 4, 6, 8, 10 and 30 min after starting vaping. Participants rated the products on a range of characteristics. The products tested included six 'cig-a-like' and two refillable products, one with variable voltage. We also tested participants' own EC.

resultsAll products significantly reduced urges to smoke. Refillable products delivered more nicotine and received generally superior ratings in terms of craving relief, subjective nicotine delivery, throat hit and vapour production but in overall ratings, they were joined by a cig-a-like, Blu. Participants puffed more on low nicotine delivery products. Participants' estimates of nicotine delivery from different EC were closely linked to 'throat hit'. Nicotine delivery was less important in the initial product ratings than draw resistance, mouthpiece comfort and effects on reducing urge to smoke.

conclusionsAll EC products reduced urges to smoke. Refillable products received generally more favourable ratings than 'cig-a-likes' with similar nicotine content. Perception of nicotine delivery was guided by throat sensations. Lower nicotine delivery was associated with more frequent puffing. The first impressions of EC products are guided less by nicotine delivery than by sensory signals.
