Between-session chasing via time of return in online eCasino gambling.
Article in Journal of behavioral addictions, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background and aims: Chasing refers to continuing and/or intensifying gambling following losses (loss-chasing) and/or wins (win-chasing). It is commonly captured between sessions, i.e., returning another day/time after losses or wins in prior sessions. Between-session chasing is a hallmark of problematic gambling, but the current understanding of between-session chasing in field settings remains limited. Methods: Using a large-scale behavioral tracking dataset (11,156 gamblers; ∼170 million bets), we assessed between-session chasing via time of return. Using pre-registered analyses, we assessed time of return as a function of (a) prior outcome (win/loss), (b) outcome magnitude, (c) game type (Multi-line Slots, Dice game, European Roulette and Multi-hand European Blackjack) and (d) gambler's involvement level (high/low; defined based on monetary and time expenditure). Results: Confirmatory results indicated that overall gamblers returned faster following a winning than a losing session. They returned faster when previous outcome magnitude (both wins and losses) increased. Furthermore, return times of slot gamblers were less sensitive to prior outcomes than other products. Exploratory results indicated that return times of high-involvement gamblers were less sensitive to prior outcome than low-involvement gamblers. Discussion and Conclusions: The current results indicate a pattern of both loss- and win-chasing, demonstrating that the break-even, house money and wealth effects may be at play. Decreased sensitivity to prior outcome among slot and high-involvement gamblers may be attributed to habituation. Future research could disentangle these multi-causal mechanisms, to evaluate time of return as a potential behavioral marker of harm, for better identification and mitigation of problem gambling.
