Bridging the gap in nutrition assessment: Barriers and knowledge impact of an educational session on body composition and energy metabolism.
Article in Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral 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
backgroundBody composition and energy metabolism assessments are central to nutrition care but remain underused. This study evaluated dietitians' access, use, education, and beliefs toward these assessments, and the impact of an educational session.
methodsDietitians (≥1 year experience) within Alberta Health Services completed online surveys on their access, use, education, confidence, and clinical protocol awareness regarding body composition and energy metabolism assessments. Participants attended a 4-h virtual educational session on these topics, with presession and postsession knowledge recall compared using Wilcoxon signed rank test.
resultsWe surveyed 36 participants (97% women), primarily from inpatient care (36%) or oncology (31%). Most (86%) never used body composition methods, despite access to computerized tomography (CT; 31%), ultrasound (US; 25%), bioelectrical impedance analysis (BIA; 6%), and dual-energy x-ray absorptiometry (DXA; 3%). Although 67% received body composition education (47% BIA, 31% DXA, 22% CT, 8% US), 64% lacked confidence. Protocol awareness was 67% for malnutrition and 8% for sarcopenia. Most never (58%) or occasionally (19%) used energy metabolism methods; Q-NRG (COSMED; 28%) and standard metabolic carts (19%) were the most available devices. Although 67% received energy metabolism education (53% metabolic cart, 31% Q-NRG), 50% were not confident in using these methods. After the educational session, body composition knowledge recall improved (median, +20% [IQR, 10-30]; P < 0.001), whereas energy metabolism scores were unchanged (P = 0.530).
conclusionDespite prior education, dietitians used body composition and energy metabolism assessments inconsistently because of limited access, insufficient applied knowledge, lack of protocols, and low confidence. These results underscore the need to strengthen curriculum and professional development to support adoption.
