Trends in reticulocyte hemoglobin equivalent values in critically ill neonates, stratified by gestational age.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
objectiveThe reticulocyte index reticulocyte hemoglobin equivalent (Ret-He) was evaluated as a marker of iron status. STUDY
designThis is a retrospective cohort study of all infants admitted to the University of Washington Neonatal Intensive Care Unit, who received Ret-He measurements as part of routine care within the first 120 days of life.
resultA total of 730 Ret-He measurements from 249 infants were analyzed (median gestational age at birth 32.1 weeks; 49 infants <28 weeks and 200 ≥28 weeks). Initial Ret-He measurements were lower in infants <28 weeks (28.24 vs. 33.34 pg). Ret-He values initially decreased, then slowly increased. Infants received an average of 3.9, 6.5, and 8.2 mg/kg/day of enteral iron sulfate at 30, 60, and 90 days, respectively.
conclusionRet-He values showed a slow uptrend with enteral iron supplementation following an initial decrease, suggesting that neonates are able to improve their iron sufficiency status with supplementation.
