The effect of demographic, financial and hospital factors on the length of stay of preterm infants: a US national database study.
Review in Journal of perinatology : official journal of the California Perinatal Association, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
introductionPreterm birth is a leading cause for prolonged length of stay (LOS) in the hospital. In the USA, the rate of preterm birth is around 10.5%, thereby contributing substantially to the burden of hospitalization. The interaction of demographic, financial, and hospital factors with LOS of preterm infants has not been studied.
objectiveTo assess the effect of demographic, financial, and hospital factors on LOS of surviving preterm infants born at 23 0/7-36 6/7 weeks of gestational age (GA).
methodsWe utilized de-identified patient information from the Healthcare Cost and Utilization Project (HCUP) from 2016-2020. All infants with GA between 23 0/7 and 36 6/7 weeks were identified. ANOVA test was used to assess LOS differences at different GA. Cochran-Armitage test was used for trend analyses.
resultsA total of 1,359,280 surviving premature infants were included in the study. LOS was significantly (p < 0.001) impacted by GA, ethnic group, hospital size and type, and US geographic region. LOS was not affected by sex or type of health insurance.
conclusionLOS of preterm infants is significantly affected by multiple demographic factors that are potentially modifiable. These findings can remarkably help policymakers and stakeholders optimize interventions and resource allocations for preterm infants.
