Food Addiction 5 and 10 Years Following Metabolic and Bariatric Surgery: a Prospective Observational Study.
Observational study in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundFood addiction (FA) is prevalent among individuals undergoing metabolic and bariatric surgery (MBS), but few studies have investigated the prevalence and correlates of post-surgical FA over longer periods. We report an observational, longitudinal study investigating prevalence of post-surgical FA at 5 and 10 years following MBS.
methodsParticipants in the Oslo Bariatric Surgery Study (OBSS) completed the modified Yale Food Addiction Scale 2.0 (mYFAS) and measures of psychological functioning and weight outcomes (% total weight loss: %TWL and % weight recurrence: %WR) at 5 and 10 years follow-up.
resultsN = 173 of 224 (23% lost-to-follow-up) participants (73% women, 93.6% Roux-en-Y gastric bypass) completed the mYFAS 2.0 at 5 years and 10 years following MBS. The prevalence of FA was 12.9% at 5 years and 8.4% at 10 years after MBS. A higher number of FA symptoms at 5 years significantly predicted less %TWL and lower psychological functioning at 10 years. At 10 years, the majority of individuals with FA had moderate or severe symptoms and 3% were new-onset cases of FA. Higher FA at 10 years was concurrently associated with less %TWL, greater %WR, and lower psychological functioning at the 10-year follow-up (p's < 0.001).
conclusionsThe prevalence of FA decreased from 12.9 to 8.4% between 5 and 10 years following MBS. We observed prospective and concurrent associations between FA symptoms and poorer weight loss and mental health outcomes. The presence of post-operative FA may be an important target for continued assessment and follow-up care to improve longer-term outcomes.
