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
Evaporation-driven self-assembly of colloidal particles in a sessile drop can construct simple structures in various scenarios. However, the non-equilibrium self-assembly process, dominated by internal capillary flow and solute- or thermal-induced Marangoni flow, cannot guarantee the precise positioning of the particles. One can exert forces on individual suspended particles by introducing external field manipulation, which enables the construction of precise deposits and even 3D structures. Here, we review recent advances in field-directed assembly techniques, including acoustics, optics, electronics, and magnetics, where micro- and nano-particles are directly guided into targeted positions to form functional structures. These techniques are fundamental in analytical chemistry for their ability to achieve precise particle positioning, which is essential for developing sensitive and specific analytical methods. We first discussed the forces generated by these external fields and then summarized the directed assembly of colloidal particles, including its benefits and disadvantages for analytical chemistry applications. Furthermore, we examine the challenges and potential solutions for controlling colloidal particles and explore future research directions to advance the field of analytical chemistry further.
