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

It is well known that nonspherical particles rotate continuously in light beams, with their rotation directions determined by the light spin. Here, we reveal that particle morphology (e.g., size, shape, length, etc.) and rotation angle are vital in influencing light-matter interactions, thereby optical torques (OTs) and forces, especially in a paraxial or slightly defocused optical system. Positive and negative OTs emerge with distinct rotation angles in light fields. Their competition can also freeze the particle's rotation, leading to the stable lateral drift effect. These extraordinary OTs arise from the nonuniformly distributed optical force vectors in the paraxial trapping. Experimentally, we observe positive and negative OTs, and bilateral drift (zero OT) of various particles (e.g., long and short cylinders, triangles, irregular shapes, etc.) under the influence of inverse optical forces and torques. Our works delve into a fascinating domain where morphologies and rotation angles of particles play essential roles in optical manipulation, enriching the fundamental understanding of optical forces and torques.
