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
objectivesLung ultrasound (LU) is effective in diagnosing the accumulation of extravascular lung water and assessing real-time fluid status in infants following congenital cardiac surgery with cardiopulmonary bypass. This study evaluated whether LU can be used as a prognostic marker for changes in noninvasive respiratory support after extubation.
methodsInfants with congenital heart disease (CHD) <1 year of age requiring mechanical ventilation for more than 24 hours postoperatively were included. Using a linear probe, 3 scan fields from each hemithorax were assessed for B-lines and consolidations, with scores ranging from 0 to 3 assigned per area. LU scores were rated then by 4 independent operators. After extubation, patients were monitored for respiratory support modifications over the following 48 hours and were divided into 3 subgroups: steady state, escalation, and de-escalation, accordingly.
resultsIn this single-center observational pilot study, a total of 30 patients with a median age of 116 (interquartile range: 17-196) days were included in the prospective analysis between July 2022 and December 2023. LU scores differed significantly among groups: 3.47 ± 2.3 (steady state), 6.14 ± 2.55 (escalation), and 1.63 ± 1.41 (de-escalation), P = .002. ROC analysis identified a cut-off score of ≥5 as predictive of escalation risk with a sensitivity of 86% and specificity of 83%. A score <2 suggested potential for de-escalation within 48 hours, with a sensitivity of 75% and specificity of 73%.
conclusionsLU scoring may be a valuable tool for optimizing ventilator weaning and post-extubation respiratory strategies in infants undergoing congenital cardiac surgery. Further studies are warranted to validate these findings.
