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
introductionBronchopulmonary dysplasia (BPD) stands as the primary chronic respiratory complication in premature infants, posing a substantial public health concern due to its rising prevalence, potential mortality, and socioeconomic burden.
aimThe aim of this study was to determine the prevalence of BPD in very preterm infants and identify its associated risk factors.
methodsWe conducted a retrospective, descriptive, and analytical study including all premature infants born between 26 and 31 weeks of gestation age (GA) who survived beyond the 28th day of life, over a five-year period (2017-2021). Patients were divided into two groups based on the presence or absence of BPD, which was defined by the need for oxygen supplementation for at least 28 days.
resultswe included 231 newborns. The prevalence of BPD was 37.7% among survivors on the 28th day of life and 36.7% among those reaching 36 weeks postmenstrual age. BPD was mild, moderate and severe in 25.2%, 4.9% and 6.6% of cases, respectively. Multivariate analysis identified maternal hypertensive disorders (RR=6.15, 95%CI=[2.27-16.67], p<0.001), chorioamnionitis (RR=4.23, 95%CI=[1.25 -14.27], p=0.02), intrauterine growth restriction (IUGR) (RR =20.4, 95%CI=[3.39 -122.66], p=0.001), GA less than 30 weeks (RR=26.97, 95%CI=[10.23 -71.14], p<0.001), and mechanical ventilation (MV) (RR=5.33, 95%CI=[1.95-14.54], p=0.001) as independent factors associated with BPD occurrence. The mortality rate was 10.3% among patients with BPD versus 0.7% in patients without BPD (p = 0.001).
conclusionOur study revealed a high prevalence of BPD in very preterm infants and identified several independent risk factors such as maternal hypertensive disorders, IUGR, chorioamnionitis, MV, and GA less than 30 weeks.
