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

This study investigates gambling behaviors among young Swiss males four years after the legalization of online casino gambling in Switzerland. A total of 2,349 conscripts aged 18 to 24 years, residing in the French-speaking region of the country, completed a paper-and-pencil questionnaire assessing their participation in land-based and online gambling, as well as problem gambling. Overall, 70.6% reported having gambled at least once in their lifetime, and 49.8% had gambled in the past 12 months. Among past-year gamblers, 58.3% engaged exclusively in land-based gambling, 34.4% were mixed (land-based and online) gamblers, and 7.3% gambled exclusively online. The majority (74.7%) accessed online gambling via smartphone or tablet. Among past-year gamblers, 4.4% met the criteria for problem gambling, representing 2.1% of the total sample. Problem gambling was associated with more frequent gambling, engagement across both online and land-based platforms, participation in a greater variety of games, and involvement in online casino gambling. In conclusion, four years post-legalization, we observe increased gambling participation, a shift from land-based to online gambling, and a slight, non-significant increase in problem gambling. Continued monitoring of gambling behaviors in this population is essential to detect and respond promptly to potential increases in problem gambling.
