Assessment of systemic circulation using ultrasound Doppler in late onset neonatal sepsis and its clinical correlation: an observational study.

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 measure the Doppler velocimetry parameters in the anterior cerebral artery (ACA), superior mesenteric artery (SMA), and main renal artery (RA) in neonates with late-onset sepsis and correlate it with associated clinical morbidities. METHODOLOGY: Prospective observational study carried out at a tertiary-level neonatal intensive care unit in India in 2022, enrolling 20 neonates with late-onset neonatal sepsis (LONS). Baseline characteristics and sepsis parameters obtained. Serial ultrasound performed on days 1, 3, and 7 from the day of clinical sepsis in the ACA, SMA, and RA and velocimetry measurements obtained. The findings were compared with 20 gestational age (GA) matched neonates in the control arm.
resultsThe mean GA of neonates with LONS was 31.03 ± 2.79 weeks and their mean birthweight was 1474 ± 509.99 g. The peak systolic velocity, resistive and pulsatility indices were significantly higher in ACA, SMA, and RA and the end-diastolic velocity was significantly lower in ACA and RA (P < 0.05) in LONS. The incidences of intraventricular hemorrhage (IVH), necrotising enterocolitis (NEC), and acute kidney injury (AKI) in neonates with LONS were 45%, 50%, and 10% respectively. A subgroup analysis of the Doppler velocimetry parameters in the neonates with LONS and for neonates with and without clinical outcomes did not suggest a significant difference.
conclusionLONS is associated with alterations in cerebral, splanchnic, and renal perfusion seen as abnormal blood flow velocimetry and vascular resistance which may predispose to IVH, NEC, and AKI.
