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

Brazil has rapidly become one of the world's largest online betting markets, raising public health and consumer-protection concerns in a newly regulated environment. Using data from a nationally representative Brazilian survey, the 2023-2024 X-Ray of the Brazilian Investor (N = 10,305), this study examined demographic, digital, financial, and psychosocial correlates of fixed-odds online betting participation. Logistic regressions showed that participation was most strongly associated with younger age, male sex, and constant internet use. Compared with adults aged 60+, respondents aged 18-34 had substantially higher odds of betting (OR = 7.30, 95% CI [5.38, 10.08]); men also had higher odds than women (OR = 2.32, 95% CI [2.04, 2.63]), as did constant internet users compared with non-users (OR = 4.62, 95% CI [2.53, 9.48]). High-risk/high-complexity investment profiles were also positively associated with betting (OR = 1.86, 95% CI [1.28, 2.68]), whereas saving was negatively associated (OR = 0.76, 95% CI [0.66, 0.88]). Findings suggest that regulatory strategies in emerging betting markets should prioritize youth exposure, digital accessibility, and intersections between gambling and speculative financial behavior.
