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

backgroundHeated Tobacco Products (HTP) are a relatively new class of tobacco products, with limited data on usage patterns. We assessed the prevalence and reasons for use among persons aged ≥15 years in 27 European Union member states and the United Kingdom·.

methodsThe 2020 Eurobarometer (93·2) survey was analysed (n=28,300, aged ≥15). Multi-level regression analyses assessed socio-demographic differences in use while separate analyses investigated reasons for starting to use HTP. Results are presented as adjusted Odds Ratios (aOR) and weighted percentages with 95% Confidence Intervals (95%CI).

findingsOverall, 6·5% (95% CI 6·1;7·0) of participants had ever used a HTP. 1·3% (1·1%;1·5%) of participants were current users of HTP, and 0·7% (0·6% to 0·9%) daily users. Current and former tobacco smokers were more likely than never tobacco smokers to use HTP (aOR 36·3 (22·9;57·5), and 7·3 (4·3;12·3) respectively. Youth aged 15-24 years of age were substantially more likely to report use, e.g. aOR for ever use=7·77 (6·56;9·21) compared to those aged ≥55 years. 51·3% of ever HTP users reported at least weekly concurrent use of combustible tobacco. Among those who reported ever use of HTP, but not e-cigarettes, the most popular reason for use was the perception that HTP are less harmful than smoking tobacco (39·5%), followed by use by friends (28·4%) and stopping or reducing smoking (28·2%).

interpretationConsiderable numbers of people in the EU have ever used HTP, although current and daily use remains low. Current use is more common among younger people, and current and former smokers.
