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

backgroundThe aspiration of gastric residual volume through the gastric tube increases the risk of feed interruption episodes, prolongs the time needed to achieve full enteral feeding and regain birth weight, and may potentially damage the gastric mucous. This study aimed to develop a point-of-care ultrasound-based model to calculate gastric residual volume in preterm infants.

methodsThis observational study enrolled 100 preterm infants who fed by gastric tube. The collected data included general characteristics of the preterm infants, the antral cross-sectional area in the right lateral position within 30 min prior to feeding and the gastric residue volume measured through gastric tube. A linear regression analysis was conducted to assess the relationship between the antral cross-sectional area and the aspirated gastric residual volume, with the calculation of the Pearson correlation coefficient. A stepwise linear multiple regression was employed to model the relationship between the suctioned residual volume and the parameters under consideration. Subsequently, we utilized the Bland-Altman plot to assess the agreement between the gastric residual volume measured by aspiration and our model, respectively.

resultsOverall, 89 preterm infants were included in the final analysis. Pearson correlation analysis revealed a significant correlation between the gastric antral cross-sectional area in the right lateral decubitus position and the suctioned volume (P < 0.001; correlation coefficient: 0.905). We developed an ultrasound calculation model as follows: Volume (ml)= -3.74 + 9.08 × Gastric Antral Cross-Sectional Area (measured in the right lateral decubitus position) (cm2). When comparing the ultrasound calculated volume and suctioned volume, the mean was 0.05 ml kg-1 and the limit of consistency was - 1.59 to 1.69 ml kg-1 between the ultrasound calculated volume and suctioned one.

conclusionThe use of ultrasound to assess gastric residual volume (GRV) offers a promising alternative to gastric tube suction, potentially reducing associated complications and enhancing enteral nutrition management in preterm infants. Our study represents a pioneering effort in the development of a point-of-care ultrasound-based calculation model for non-invasive GRV assessment in this vulnerable population.
