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
objectiveThis study aimed to investigate whether the mode of delivery influences intestinal microperfusion in healthy term neonates and to evaluate the utility of Superb Microvascular Imaging (SMI) in assessing neonatal intestinal microcirculation.
methodsA total of 45 healthy term neonates born between 38 and 40 weeks of gestation were prospectively enrolled. Twenty-six infants were delivered by cesarean section (C/S) and 19 by normal spontaneous vaginal delivery (NSVD). Intestinal microperfusion was assessed within the first 48 hours of life using monochrome SMI (mSMI) and color SMI (cSMI). Conventional Doppler techniques, including Color Doppler Imaging (CDI), Power Doppler Imaging (PDI), and Advanced Dynamic Flow (ADF), were also performed. Intestinal vascularity was semi-quantitatively scored and compared between groups.
resultsNo significant difference in intestinal microperfusion was observed between neonates delivered by C/S and NSVD using either mSMI (p=0.507) or cSMI (p=0.720). Similarly, no significant differences were detected using CDI, PDI, or ADF. However, mSMI demonstrated significantly higher detection of intestinal vascularity compared to cSMI (p<0.0001) and conventional Doppler modalities, which failed to detect vascular signals in a substantial proportion of cases.
conclusionMode of delivery does not appear to significantly affect early intestinal microperfusion in healthy term neonates. Superb Microvascular Imaging, particularly mSMI, provides a sensitive and non-invasive method for visualizing neonatal intestinal microcirculation. These findings support the potential role of SMI in establishing reference perfusion patterns and in the early detection of gastrointestinal perfusion abnormalities in neonates.
