Mechanisms of postoperative anorexia in surgical patients: a narrative review.
Review in Frontiers in neuroscience, 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
Postoperative anorexia is a highly prevalent condition among surgical patients, which exerting a profound impact on their recovery trajectories and nutritional status. The underlying mechanisms are complex and multifactorial, including neuroendocrine dysregulation, activation of inflammatory signaling pathways, and the interaction between psychological processes and pathological conditions. Emerging evidence underscores the significant role of altered hunger and satiety perception, cognitive modulation of food-related cues, and emotion-driven behavioral responses in the regulation of postoperative appetite. Despite these insights, there are currently no definitive targeted interventions available to effectively restore appetite in the postoperative setting. This narrative review summarizes recent advances in the understanding of appetite regulation, delineates key biological and psychosocial factors contributing to postoperative anorexia, and systematically synthesizes current clinical assessment approaches, and discusses emerging therapeutic strategies. By integrating insights from physiology, cognition, and affective science of postoperative anorexia, this narrative review seeks to provide a comprehensive understanding of the pathogenesis, assessment, and the current therapeutic strategies of postoperative anorexia.
