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

Introduction: Snus may present lower health risks than cigarettes, but its harm reduction potential may be undermined if used dually with cigarettes. The likelihood of exclusive snus use compared with dual use may depend in part on the capacity of snus to deliver nicotine in doses that are satisfactory to smokers. We examined characteristics of "American snus" products, including nicotine levels, and compared to snus products that are more typical of Sweden. Methods: Tobacco industry reports for snus products submitted to the Massachusetts Department of Public Health for the year 2014 were used to assess moisture (%), pH, total nicotine, and unionized (free) nicotine (both mg/g and percent of total). A total of 14 ("American") snus products made by American manufacturers Philip Morris USA (n = 6), R.J. Reynolds Tobacco Company (n = 6), and US Smokeless Tobacco Company (n = 2), were compared with Swedish-style ("Swedish") snus products (n = 10) made by Swedish Match North America. Results: Compared with Swedish snus, American snus brands contained significantly lower concentrations of unionized nicotine (median: 0.52 mg/g vs. 6.52 mg/g; p < .001) and proportion of unionized nicotine (median: 3.17% vs. 81.8%; p < .001). American snus brands also had significantly lower pH (median: 6.54 vs. 8.68; p < .001) and moisture (median: 30.3% vs. 53.4%; p < .001). Conclusions: Swedish-made snus has higher unionized nicotine, measured by concentration and proportion of total nicotine, compared with snus products made by American manufacturers. These findings suggest that American snus products have lower addiction potential than Swedish snus, and may be more likely to be used dually with cigarettes than as a sole source of nicotine. Implications: American snus products contain significantly lower unionized nicotine, lower pH, and lower moisture, compared with Swedish snus products. Snus addiction potential and patterns of usage, including co-use with cigarettes, may differ between American and Swedish snus products due to differences in snus product characteristics.
