Quantitative assessment of gastrointestinal motility in neonatal rats by real-time 3D photoacoustic imaging: A feasibility 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
Gastrointestinal (GI) motility assessment in neonates remains challenging for conventional clinical imaging. We present a preliminary quantitative framework for GI dynamics in healthy neonatal rats using a real-time three-dimensional photoacoustic imaging system, enabling high-contrast visualization of gastric and intestinal structures. India ink was administered orally as a contrast agent to enhance visualization of the GI tract. We developed a dual-branch analysis pipeline including spatiotemporal kymography for local rhythmic activity quantification and cluster tracking for transport-pattern classification. In healthy neonatal rats, intestinal rhythmic activity was measured at 9.25 ± 0.96 cycles per minute, while gastric peristaltic waves were identified from kymographs. Tracking of contrast-agent clusters revealed local propulsive and retrograde transport patterns, while segmental-like activity was identified from cluster-splitting events. This feasibility study demonstrates a volumetric GI imaging and analysis method for neonatal GI kinematics, laying a foundation for future larger-scale validation and disease-model studies.
