1 · What the graph read from it

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.

2 · The registry

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

Photoacoustic tomography (PAT) is a promising tool for non-invasive vascular imaging, yet conventional linear scanning suffers from "limited-view" artifacts and structural discontinuities due to restricted transducer acceptance angles. To overcome these physical bottlenecks, we propose a robot-assisted wide-amplitude oscillatory (WAO) scanning strategy. By integrating controlled lateral harmonic oscillations into axial linear trajectories via a 6-DoF robotic arm, this method achieves kinematic modulation to physically synthesize a dynamic aperture. This approach effectively captures high-frequency acoustic information typically lost in single-path scans, compensating for hardware-based detection limits. Numerical simulations and a preliminary
