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

objectiveTo identify the population of Internet e-cigarette vendors (IEVs) and conduct content analysis of products sold and IEVs' promotional, claims and pricing practices.

methodsMultiple sources were used to identify IEV websites, primarily complex search algorithms scanning over 180 million websites. In 2013, 32 446 websites were manually screened, identifying 980 IEVs, with the 281 most popular selected for content analysis. This methodology yielded 31 239 websites for manual screening in 2014, identifying 3096 IEVs, with 283 selected for content analysis.

resultsWhile the majority of IEVs (71.9%) were US based in 2013, this dropped to 64.3% in 2014 (p<0.01), with IEVs located in at least 38 countries, and 12% providing location indicators reflecting two or more countries, complicating jurisdictional determinations.Reflecting the retail market, IEVs are transitioning from offering disposable and 'cigalike' e-cigarettes to larger tank and "mod" systems. Flavored e-cigarettes were available from 85.9% of IEVs in 2014, with fruit and candy flavors being most popular. Most vendors (76.5%) made health claims in 2013, dropping to 43.1% in 2014. Some IEVs featured conflicting claims about whether or not e-cigarettes aid in smoking cessation. There was wide variation in pricing, with e-cigarettes available as inexpensive as one dollar, well within the affordable range for adults and teens.

conclusionsThe number of Internet e-cigarette vendors grew threefold from 2013 to 2014, far surpassing the number of Internet cigarette vendors (N=775) at the 2004 height of that industry. New and expanded regulations for online e-cigarette sales are needed, including restrictions on flavors and marketing claims.
