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
objectivesTo evaluate the efficacy of noninvasive ventilation combined with vibrating mesh nebulization of pulmonary surfactant (PS) in preterm infants with respiratory distress syndrome (RDS) and to identify predictors of treatment failure.
methodsPreterm infants with RDS (gestational age >28 weeks, birth weight >1 000 g) admitted to neonatal intensive care units at 12 hospitals between June 2023 and November 2024 were prospectively enrolled. All infants initially received nasal continuous positive airway pressure and were treated with PS administered via vibrating mesh nebulization. Infants were categorized into a success group or a failure group according to whether escalation to invasive mechanical ventilation via endotracheal intubation was required. Multivariable logistic regression was used to identify predictors of failure of vibrating mesh nebulized PS treatment. A prediction model was constructed, and its performance was assessed using receiver operating characteristic (ROC) curves and the area under the curve (AUC).
resultsA total of 126 preterm infants with RDS were included, with 107 (84.9%) in the success group and 19 (15.1%) in the failure group. Multivariable logistic regression analysis showed that nonstandard antenatal glucocorticoid use, a lower 1-minute Apgar score, chest radiograph showing RDS grade ≥III, and a lower ratio of partial pressure of arterial oxygen (PaO
conclusionsNoninvasive ventilation combined with vibrating mesh nebulization of PS achieves a high success rate in preterm infants with RDS who had a gestational age >28 weeks and a birth weight >1 000 g. Nonstandard antenatal glucocorticoid use, a 1-minute Apgar score <8, chest radiograph showing RDS grade ≥III, and PaO
