Pulmonary Peak Flow Assessment: An Easy Tool for Cardiac Output Estimation in Hemodynamically Stable Neonates.

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
Objectives: Right ventricular output (RVO) assessment can estimate systemic blood flow (SBF) in neonates but requires advanced echocardiography expertise. Pulmonary peak flow (PPF) could be an easier surrogate for RVO. This study is aimed at evaluating the correlation between RVO and PPF in neonates and assessing their intraobserver variability. Methods: In this single-center, longitudinal, observational study, we included term and preterm neonates admitted to our Neonatal Intensive Care Unit between February and July 2022. A neonatologist with experience in functional echocardiography recorded targeted neonatal scans. Recordings were analyzed off-line for echocardiographic measurements. After 12 months, a second analysis of the recordings was performed by the same examiner to avoid recall bias. We compared the two analyses for intraobserver variability assessment. Results: We analyzed a cohort of 33 term and preterm infants. We found a strong positive correlation between RVO and PPF ( Conclusions: Our findings support the use of PPF as a surrogate for RVO for cardiac output estimation in term and preterm neonates. Because of its simplicity, rapidity, and low intraobserver variability, PPF could be a useful tool for SBF assessment. Future studies should be performed to evaluate the correlation between PPF and other echocardiographic markers of low SBF.
