Meal composition and nutrient intake in hospitalized adults: the role of relative energy and protein content.
Article in European journal of clinical nutrition, 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
BACKGROUND/
objectiveInadequate oral intake among hospitalized adults contributes to malnutrition and adverse outcomes. While guidelines advocate meals with higher energy and protein content, how meal composition relates to intake under routine conditions is unclear. SUBJECTS/
methodsIn this cross-sectional study, 392 lunch and dinner meals were recorded across six departments at a tertiary hospital. Intake was measured by weighing food before and after consumption, and nutrient content was derived from standardized recipes and food composition tables. Meals were stratified by relative energy and protein content (per 100 g food), categorized as above or below the median. Associations between meal composition and intake outcomes were analyzed using non-parametric tests (Mann-Whitney U and Kruskal-Wallis).
resultsMedian consumption was 205 g [IQR: 119-286], providing 250 kcal [137-385] and 10.0 g [5.8-15.6] of protein per meal. Meals above the median for relative energy content were associated with higher energy (+117 kcal; p < 0.001) and protein intake (+3.6 g; p < 0.001) compared with meals below the median, with no difference in food weight. Meals above the median for relative protein content provided +4.9 g more protein (p < 0.001) despite a 23 g reduction in weight (p = 0.007).
conclusionsHospitalized patients consume modest energy and protein. Higher relative energy and protein content of foods was associated with greater intake despite similar or smaller portions. These findings support targeted meal-composition strategies focusing on energy and protein enrichment.
