The effects of roux en y gastric bypass surgery on neurobehavioral symptom domains associated with severe obesity.
Article in Physiology & behavior, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundNeurobehavioral symptoms and cognitive dysfunction related to mood disorders are present in individuals with severe obesity. We sought to determine acute improvements in these symptoms and relationships with adiposity, inflammation, and insulin sensitivity after roux-en-y gastric bypass (RYGB) surgery.
methodsThe self-report Zung Depression Rating (ZDRS) and Neurotoxicity Rating (NRS) scales were administered before, and at 6-months after RYGB surgery in severely obese women (body mass index > 35 kg/m
resultsBy 6-months after RYGB, VAT, SAT, Si, CRP, and IL-6 had improved (p < .05). Anxiety, somatic, and neurovegetative symptoms domains improved (p < .05), but depressed mood/suicidal ideation and cognitive domains did not. Reductions in VAT were associated with decreases in neurovegetative symptoms (beta = 295 ± 85, p < .01). We also found significant positive longitudinal associations between IL-6 concentrations and minor changes in cognitive symptoms.
conclusionAnxiety, somatic and neurovegetative symptoms, improved within 6 months after RYGB, but depressed mood/suicidal ideation and cognitive symptoms did not improve. Associations between visceral adiposity, IL-6 concentrations and neurovegetative and cognitive symptoms support links between obesity, inflammation and distinct neurobehavioral symptoms.
