1 · What the graph read from 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.

2 · The registry

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

backgroundBurn injury results in increased skeletal muscle protein turnover, where the magnitude of protein breakdown outweighs synthesis, resulting in muscle wasting. The effect of increased amino acid (AA) provision on skeletal muscle fractional synthesis rate (FSR) in severely burned patients during their convalescence after discharge from hospital is not known. Subsequently, the purpose of this study was to determine skeletal muscle FSR in response to AA infusion in severely burned pediatric patients at discharge from hospital and at 6 and 12 months after injury.

methodsStable isotope infusion studies were performed in the fasted state and during intravenous AA infusion. Skeletal muscle biopsies were obtained and isotope enrichment was determined to calculate skeletal muscle FSR. Patients were studied at discharge from hospital (n = 11) and at 6 (n = 15) and 12 months (n = 14) after injury.

resultsThe cohorts of patients studied at each time point after injury were not different with regard to age, body mass, or burn size. AA infusion failed to stimulate FSR above basal values at discharge from hospital (mean [SEM]: 0.27% [0.04%] vs. 0.26% [0.06%] per hour), 6 months after injury (0.20% [0.04%] vs. 0.22% [0.03%] per hour), and 12 months after injury (0.16% [0.03%] vs. 0.15% [0.03%] per hour). Daily FSR was numerically lower at 6 months after burn (5.13% [0.78%] per day) and significantly (p < 0.05) lower at 12 months after burn (3.67% [0.65%] per day) relative to discharge group (6.32% [1.02%] per day). DISCUSSION: The findings of the current study suggest that the deleterious effect of burn injury on skeletal muscle AA metabolism persists for up to 1 year post burn. In light of these findings, nutritional and pharmacological strategies aimed at attenuating muscle protein breakdown post burn may be a more efficacious approach to maintaining muscle mass in severely burned patients. LEVEL OF EVIDENCE: Prognostic study, level II.
