Impact of Nutrition on Somatotroph Axis: A Potential Role in Acromegaly and Its Cardiovascular Risk?
Review in Journal of the Endocrine Society, 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
Diet composition and energy intake directly modulate the growth hormone (GH) and insulin-like growth factor 1 (IGF-1) axis, and indirectly through endogenous regulators such as insulin, ghrelin, and adipokines. Moreover, diet has a well-established role in the prevention and management of various metabolic and cardiovascular comorbidities in the general population. Acromegaly, caused by an endogenous overproduction of GH, is an endocrine disorder associated with increased risk of metabolic and cardiovascular comorbidities and excess mortality. The treatment of acromegaly aims to normalize GH and IGF-1 levels, manage complications, and reduce mortality. There is a considerable gap in research regarding the specific influence of diet on biochemical control and complications in acromegaly; therefore, consensus guidelines for managing metabolic and cardiovascular complications in acromegaly generally recommend the same nutritional interventions as those for the general population, even though the underlying pathogenic mechanisms often differ. This narrative review aims to provide an overview of how nutrition modulates the GH/IGF-1 axis and to summarize current evidence on the effect of various macronutrients and dietary patterns on biochemical control and comorbidity management in patients with acromegaly. Evidence in healthy individuals suggests that diets low in animal-derived proteins, combined with moderate fat and carbohydrate intake, may lower GH/IGF-1 activity. Nevertheless, further research is needed in patients with acromegaly to determine whether dietary interventions, such as those found effective in the general population, can help achieve biochemical control and effectively manage metabolic and cardiovascular comorbidities in this specific group.
