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

We measured levels of nitrosonornicotine (NNN) and 4-[methyl(nitroso)amino]-1-(3-pyridinyl)-1-butanone (NNK), the two most carcinogenic tobacco-specific nitrosamines, in the filler, binder, and wrapper of 50 cigars: 19 large cigars, 23 cigarillos, and 8 little cigars. The average NNN and NNK levels were 10.6 and 3.70 μg/g, respectively. These levels are 5- and 7-fold higher, respectively, than those of commercial cigarettes. The differences in NNN and NNK levels between cigars and cigarettes reflect differences in tobacco blends and tobacco treatments, such as fermentation. The average tobacco NNN and NNK levels of large cigars were 3- and 5-fold higher than those of cigarillos and little cigars, respectively. Large cigars also exhibited a significantly broader range of NNN and NNK than cigarillos and little cigars. The NNN and NNK levels in cigarillos are comparable to those of little cigars. These results are consistent with earlier studies finding that cigarillos and little cigars have similar tobacco blends with lower NNN and NNK content than large cigar tobacco blends.
