Dietary Macronutrient Composition and Risk of Radiation-Induced Acute Skin Toxicity in Women with Breast Cancer: Results from the ATHENA Project.
Observational study in Nutrients, 2024. 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
backgroundThe impact of the dietary macronutrient composition and its subcomponents (saccharides, fatty acids, and protein sources) on radiation-induced acute skin toxicity (AST) in breast cancer (BC) patients is unknown. Hence, we examined the association between dietary macronutrients and their subcomponents and the risk of ≥grade 2 (G2) AST post-radiotherapy among women with BC.
methodsAn observational study was conducted among 161 BC patients treated with radiotherapy and enrolled in the ATHENA project in Italy. Habitual dietary intake was assessed at study entry (T0) using a 188-item food frequency questionnaire (FFQ). AST was measured at T1 (after 3 or 5 weeks of radiotherapy) and defined according to the Radiation Therapy Oncology Group criteria. A prospective analysis used multivariable-adjusted logistic regression models to examine the association between the dietary macronutrient composition and its subcomponents at T0 and the odds of ≥G2 AST post-radiotherapy.
results≥G2 AST post-radiotherapy was observed in 43 (27%) patients. Among dietary macronutrient models, a higher intake of dietary carbohydrates was positively associated with a 30% higher odds of ≥G2 AST post-radiotherapy (OR = 1.30; 95% CI 1.01 to 1.67; for 30 g/d). Conversely, a higher dietary protein intake was inversely associated with a 76% lower odds of ≥G2 AST post-radiotherapy (OR = 0.24; 95% CI 0.06 to 0.91; for 30 g/d). There was no association with dietary fat. In macronutrient subcomponent models, only animal protein was inversely associated with a 51% lower odds of ≥G2 AST post-radiotherapy (0.49; 95% CI 0.25 to 0.95; for 15 g/d).
conclusionsDietary carbohydrates were associated with a higher risk of radiation-induced AST among women with BC, whereas dietary protein, especially animal protein, was associated with a lower risk. Cautiously balancing carbohydrate and protein intakes could be a part of the clinical management strategy for ≥G2 AST reduction post-radiotherapy among BC women.
