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
aimTo examine the population pattern of bronchopulmonary dysplasia (BPD), death and composite outcome (BPD/death) in preterm infants in Australia.
methodsA retrospective population study using linked statewide health administrative data between 2005 and 2015 to estimate the incidence of BPD, death and composite outcome stratified by gestation: extremely preterm (EPT), very preterm (VPT) and moderate-to-late preterm (MPT). Associated risk factors were analysed using generalized estimating equation logistic regression models.
resultsOf 1 047 885 live births, 73 314 (7%) were preterm, of whom 1906 died and 1898 developed BPD (25.9/1000). BPD incidence was highest in EPT (324.6/1000), followed by VPT (89.7/1000) and MPT (1.5/1000) infants. Annual BPD incidence increased from 23.5 (in 2005) to 28.0/1000 (in 2015) (p < 0.001), while composite outcome marginally decreased from 55.3 to 46.3/1000 (p = 0.629), driven by reduced mortality (32.5 to 18.8/1000) (p < 0.001). Among 10 407 < 32 weeks infants, risk factors for BPD, death and composite outcomes were born EPT (aOR ranging 8.5-13.35), assisted vaginal/breech delivery (aOR 1.25-1.41), small-for-gestational-age (aOR 3.27-3.88), male sex (aOR 1.21-1.42) and had low 5-min APGAR score (aOR 1.64-12.47).
conclusionThe rising BPD incidence, predominantly among EPT survivors, was offset by reduced overall preterm mortality. Findings call for healthcare planning to cater for increased BPD survivors.
