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

Microrobotics technology shows great potential in the field of minimally invasive medicine but still faces key challenges regarding motion control, safety, and cost. Hence, a near-infrared light-response bilayer actuator is designed in this work. The light-driving mechanism and its application in the light-controlled drug release capsule system is deeply explored by taking the double-layer polyvinyl alcohol (PVA)-carbon nanotube (CNT)/polyethylene (PE)-graphene oxide (GO) (PVA-CNT/PE-GO) composite films as the core actuating material. Due to the significant mismatch in thermal expansion coefficients between PVA and PE, the film achieves large bending deformation with a rapid response under NIR irradiation, demonstrating excellent actuation performance. Furthermore, the effects of CNT concentration gradients and PVA-CNT layer thickness on the performance of the flexible films are analyzed to ensure superior stability and fatigue resistance. Additionally, based on COMSOL finite element simulations, a "light-thermal-mechanical" energy conversion model is proposed to validate the thermal response and actuation mechanism of the composite films. Ultimately, based on the light-response bilayer actuator, a light-controlled capsule is designed to demonstrate the photothermal actuation and on-demand opening, providing a design strategy for light-response actuators with potential for further biomedical exploration.
