Echocardiographic predictors of adverse outcomes in infants with congenital diaphragmatic hernia.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 determine the relationship between echocardiography indices of heart function and adverse short-term outcomes in infants with congenital diaphragmatic hernia (CDH). STUDY
designThis was a retrospective cohort study of infants with CDH from four neonatal surgical centres between 2018 and 2021. Serial targeted neonatal echocardiography was performed to assess myocardial function. The composite primary outcome was death or invasive mechanical ventilation beyond postnatal day 14.
resultsWe identified 44 infants, and 18 (40.9%) met the composite primary outcome. They had lower pre-operative left ventricular output (110 vs. 157 mL/kg/min, p = 0.002), right ventricular output (114 vs. 187 mL/kg/min, p = 0.008), and peak systolic myocardial velocities measured at the mitral annulus (4.6 vs. 5.4 cm/s, p = 0.006) and interventricular septum (4.2 vs. 4.8 cm/s, p = 0.001). They exhibited lower post-operative right ventricular output (155 vs. 237 mL/kg/min, p = 0.021) and lower myocardial velocities on tissue Doppler imaging.
conclusionEchocardiographic assessments may provide critical prognostic information regarding post-operative respiratory trajectories.
