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
backgroundPulmonary edema is a clinically significant complication in children with congenital heart disease (CHD). It occurs more frequently in complex cases and is associated with prolonged hospital stays. Early identification is essential because of its direct impact on clinical outcomes.
objectivesTo evaluate lung ultrasonography (LUS) as a diagnostic tool for pulmonary edema and to identify associated clinical and laboratory factors in children with CHD.
methodsChildren with CHD who underwent LUS between September 2020 and September 2023 were included. LUS findings were compared with clinical data, chest radiography results, and B-type natriuretic peptide (BNP) levels. Patients were classified according to pathophysiological category (pulmonary overflow, pulmonary hypertension, or other).
resultsA total of 62 children were evaluated, with a median age of 5.5 months (interquartile range, 4-10.1 months). Pulmonary overflow was identified in 49 patients (79%), pulmonary hypertension in seven (11.3%), and other pathophysiological conditions in six (9.7%). The median BNP level was 815.5 pg/mL. Pulmonary edema was detected in 36 patients (58%) by chest radiography and in 33 patients (53%) by LUS. A significant overlap was observed, as 79% of patients with positive LUS findings also demonstrated edema on chest radiography (p < 0.001). In contrast, only 34.5% of patients with negative LUS findings had radiographic evidence of edema. Pulmonary edema was significantly associated with recurrent lower respiratory tract infections, underweight status, body mass index below -2 standard deviations, and increased BNP levels. Multivariate logistic regression analysis identified failure to thrive as an independent predictor of pulmonary edema. Chest radiography findings remained the primary factor associated with pulmonary edema.
conclusionLUS is a reliable, radiation-free modality for detecting pulmonary edema in children with CHD. Identification of associated risk factors may facilitate early recognition of vulnerable patients and support timely, appropriate clinical interventions.
