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
objectiveTo evaluate the knowledge and clinical practices of pediatric intensivists in Brazil regarding the Pediatric Acute Lung Injury Consensus Conference 2 (PALICC-2) definitions and management of pediatric acute respiratory distress syndrome.
methodsA nationwide online survey was conducted between February and August 2025 among pediatric intensive care unit physicians. The questionnaire assessed demographics, training, knowledge of the PALICC-2 diagnostic criteria, and preferred management strategies in response to a case vignette. Responses were analyzed descriptively.
resultsA total of 212 intensivists participated, of whom 158 completed the survey. Most respondents were female (67%), aged 31 - 40 years (50%), and had been out of school for 11 - 20 years (39%). The majority completed both general pediatrics and pediatric intensive care residency training (70%). For ventilatory management, 48.5% used a tidal volume of 4 - 6mL/kg, while 46.3% used 6 - 8mL/kg; 81% selected titration of optimal positive end-expiratory pressure; only 39% used a protective plateau pressure; 71.3% used a driving pressure limited to 15cmH2O. Analgesia strategies most frequently included neuromuscular blockade optimization (85%). In a case vignette, 88.8% correctly recognized severe pediatric acute respiratory distress syndrome according to PALICC-2 criteria, and nearly all (98.9%) classified the case as severe. In the event of deterioration despite optimized conventional therapies, 87% indicated extracorporeal membrane oxygenation as their rescue strategy.
conclusionBrazilian pediatric intensivists demonstrated fair knowledge of PALICC-2 definitions, though they had some concerns about recognizing pediatric acute respiratory distress syndrome. Variability in management strategies underscores the need for continued dissemination of standardized guidelines and training to improve adherence and optimize outcomes.
