Parenteral nutrition and bioelectrical impedance analysis estimated fat-free mass in adult patients with chronic intestinal failure: A descriptive cohort study.

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
backgroundIn patients with chronic intestinal failure, the content and type of parenteral nutrition are individually determined based on various factors, including body composition. In clinical practice, bioelectrical impedance analysis is used to assess body composition using standardized protocols. However, these protocols lack specific recommendations for patients receiving parenteral nutrition. Therefore, this study described the effect of parenteral nutrition infusion on fat-free mass as evaluated by single-frequency bioelectrical impedance analysis.
methodsWe performed a descriptive cohort study using bioelectrical impedance analysis to assess adult patients with chronic intestinal failure receiving parenteral nutrition. Measurements were performed at baseline (before parenteral nutrition infusion) and 0, 1, 2, and 4 h after (usually) 18-h parenteral nutrition infusion using hand-to-foot single-frequency bioelectrical impedance analysis (Bodystat 500). The primary outcome of fat-free mass was calculated using the Kyle equation. A linear mixed model was used to compare baseline values with other time points. A difference of >1 kg in fat-free mass compared with baseline was considered clinically relevant.
resultsTwenty patients (70% female) with a mean age of 58 (SD, 14) years and a median body mass index of 22.3 (IQR, 21.2-24.8) kg/m
conclusionThis study found that parenteral nutrition infusion does not affect fat-free mass estimation as assessed by hand-to-foot single-frequency bioelectrical impedance analysis.
