Volumetric Analysis of Gallbladder in Extremely Premature Infants.
Article in Journal of medical ultrasound. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWe hypothesized that gallbladder (GB) volume is affected by serial changes during the early infancy period in extremely premature infants.
methodsWe conducted a prospective study of extremely premature infants admitted to the neonatal intensive care unit of Fukushima Medical University Hospital, Fukushima City, Japan between January 2014 and December 2015. GB volume was measured by an abdominal ultrasound ellipsoid method between Day 0 and Day 56 after birth within 60 minutes before enteral feeding. We calculated GB volume (mL)/weight (kg), which was evaluated as GV/W.
resultsIntotal, 30 infants were included. Themediangestationalageoftheinfantswas 26 weeks 5 days (range, 23 weeks 1 day-28 weeks 6 days), and the median birth weight was 731 g (range, 398-1220 g). The detection rate of GB decreased in the infants over time; the rates were > 93% between Day 0 and Day 7 and < 77% between Day 10 and Day 56 after birth. GV/W decreased in the infants over time. The median GV/W values were 0.18 (range, 0.05 -0.59) in infants on admission and constantly < 0.05 in those between Day 10 and Day 56 after birth. There was no correlation of GV/W with clinical variables after birth.
conclusionIt is considered that GB volume is not affected by serial changes without nonfavor-able course of enteral nutrition.
