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.

2 · The registry

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

backgroundLung ultrasound could be useful tool in prediction and management of bronchopulmonary dysplasia (BPD).

aimThis study aimed to assess the effectiveness of the extended lung ultrasound (eLUS) score and posterior zone assessment in predicting BPD. SETTING AND

designProspective cohort study held at the Neonatal-Intensive-Care Unit of Alexandria-University-Maternity-Hospital between November-2024 and May-2025.

methodsA total of 100 neonates with gestational age < 32 weeks, still requiring respiratory support on day-7, had regular LUS on days 7, 14, and 28 postnatally. They were categorized into two groups: BPD and non-BPD. A comparative analysis was performed between the groups. The predictive power of LUS for BPD development at 36 weeks of postmenstrual age was evaluated by ROC curve analysis.

resultsThe mean (SD) gestational age for the entire group was 29.52 ± 1.05 weeks. Infants who developed BPD exhibited statistically higher eLUS scores on both day-7 and day-14 afterbirth (P < 0.001). A day-7 eLUS and posterior zones score cutoff of more than 13 and more than 4 points, respectively, predicted BPD with a sensitivity of 97% and 97.1% and a specificity of 92% and 89.39%. The eLUS score on day-7 exhibited a strong correlation with invasive mechanical ventilation (IMV) on day-7, the duration of IMV, and oxygen saturation index.

conclusionsBoth eLUS score and posterior zones at day-7 strongly predicts BPD in preterm-infants. Evaluating posterior lung zones appears crucial for improving LUS diagnostic accuracy. LUS scores increased with increasing BPD severity.
