Article in Pediatrics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01825499 (Vermont Oxford Network Very Low Birth Weight Database of Infants <=1500 Grams or <=29 Weeks Gestational Age at Birth), which is not on this map.

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.

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.

Abstract

BACKGROUND AND

objectivesThe

methodsRetrospective cohort study of infants born from 22 to 29 weeks' gestation in 2018 at 715 US hospitals in the Vermont Oxford Network. Rates of BPD, major neonatal morbidities, and common respiratory therapies, stratified by BPD severity, were determined.

resultsAmong 24 896 infants, 2574 (10.3%) died before 36 weeks' postmenstrual age (PMA), 12 198 (49.0%) did not develop BPD, 9192 (36.9%) developed grade 1 or 2 BPD, and 932 (3.7%) developed grade 3 BPD. Rates of mortality before 36 weeks' PMA and grade 3 BPD decreased from 52.7% and 9.9%, respectively, among infants born at 22 weeks' gestation to 17.3% and 0.8% among infants born at 29 weeks' gestation. Grade 1 or 2 BPD peaked in incidence (51.8%) among infants born at 25 weeks' gestation. The frequency of severe intraventricular hemorrhage or cystic periventricular leukomalacia increased from 4.8% among survivors without BPD to 23.4% among survivors with grade 3 BPD. Similar ranges were observed for late onset sepsis (4.8%-31.4%), surgically treated necrotizing enterocolitis (1.4%-17.1%), severe retinopathy of prematurity (1.2%-23.0%), and home oxygen therapy (2.0%-67.5%).

conclusionsMore than one-half of very preterm infants born in the United States died before 36 weeks' PMA or developed BPD. Greater BPD severity was associated with more frequent development of major neonatal morbidities, in-hospital mortality, and use of supplemental respiratory support at discharge.
