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.
PubMed lists nothing against this paper. Absence here is not a guarantee, only a check that was made.

Individuals who undergo metabolic bariatric surgery (MBS) and have high preoccupation with and drive to consume palatable foods are at risk of overeating and suboptimal outcomes after MBS. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique, shows promise for altering cognitive aspects of food reward. Yet, no study has examined rTMS effects on behavioral aspects of food reward in the context of MBS. This preliminary investigation administered rTMS to the left dorsolateral prefrontal cortex (using Montreal Neurological Institution coordinates of - 50, 30, 36) to reduce the relative-reinforcing value of food (RRV-i.e., how much effort an individual is willing to expend to obtain food compared to other rewards) in preoperative MBS patients. On separate testing days, participants completed an RRV task that compared how hard they would work for food versus money before and after random, counterbalanced assignment to active- or sham-rTMS. Higher RRV scores indicated a greater willingness to work for food relative to money. Of 12 participants randomized, 10 (40% male, 47.9 ± 4.8 years old; BMI = 45.1 ± 5.1 kg/m
