Effect and feasibility of the combination of branched chain amino acid and exercise therapy on muscle mass and echo intensity of muscle in orthopedic patients in a convalescent rehabilitation hospital: A crossover trial.
Article in Health science reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 and Aims: This study examined the feasibility of nutritional support combined with exercise intervention for restoring muscle and physical functions in convalescent orthopedic patients. Methods: We used a crossover design in which nutritional support combined with exercise intervention was administered daily during the early (1 month) and late (1 month) cycles with a 1-week washout period. The exercise intervention was performed twice daily for 2 months in the early and late groups. The exercise intervention consisted of one set of muscle strength, stretching, and physical activity exercises for 20 min each. Nutritional interventions were administered immediately after the exercise. A 3.4 g of branched-chain amino acid supplements (BCAAs) or 1.2 g of starch was ingested. We measured the skeletal muscle mass and isometric muscle strength of the limbs and performed balance tests. After the crossover, the BCAA and Placebo groups were compared. Results: The ratio of improvement in the echo intensity of the rectus femoris (RF) was significantly higher in the BCAA group. A comparison of the order of nutritional intervention showed a significant effect on the RF echo intensity in both groups only when BCAAs were administered. Conclusion: This study's results suggest that the proposed combined intervention improves muscle quality and mass in convalescent orthopedic patients.
