Influence of body composition on energy metabolism in females with constitutional thinness.
Article in European journal of clinical nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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/
objectivesIndividuals with constitutional thinness are characterized by an atypical resting energy metabolism and body composition. The aim of the present study was to compare patterns of energetic changes from a fasted resting state to i) postprandial resting, ii) fasted exercise, and (iii) postprandial exercise between females with constitutional thinness and normal-weight, considering body weight and composition characteristics. SUBJECTS/
methodsBody composition (X-ray absorptiometry) and maximal aerobic capacities were assessed in 17 female adults with constitutional thinness and 17 normal-weight controls. Their energy expenditure and substrate oxidation were assessed by indirect calorimetry on four occasions: i) in a fasted resting state, ii) two hours after a calibrated meal in a resting state, iii) after a 30-min cycling exercise performed postprandially, and iv) after a 20-min walking exercise in a fasted state.
resultsFemales with constitutional thinness had significantly lower body weight (p < 0.001), absolute fat-free mass (p < 0.001) and percentage of fat mass (p = 0.04). Energy expenditure was lower for all the energetic stimuli considered (from p = 0.02 to p < 0.001) in participants with constitutional thinness compared to normal-weight controls, and differences disappeared after adjustment for body weight or composition.
conclusionsThe present results do not indicate any impaired energetic responses to any energetic stimuli in females with constitutional thinness. Results challenge the hypothesis of a spender energy profile in individuals with constitutional thinness, and highlight the necessity to gain insight into the role of body composition in energetic regulation in this population.
