Strain-Multiplex Metalens Array for Tunable Focusing and Imaging.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Metalenses on a flexible template are engineered metal-dielectric interfaces that improve conventional imaging system and offer dynamic focusing and zooming capabilities by controlling the focal length and bandwidth through a mechanical or external stretch. However, realizing large-scale and cost-effective flexible metalenses with high yields in a strain-multiplex fashion remains as a great challenge. Here, single-pulsed, maskless light interference and imprinting technique is utilized to fabricate reconfigurable, flexible metalenses on a large-scale and demonstrate its strain-multiplex tunable focusing. Experiments, in accordance with the theory, show that applied stretch on the flexible-template reconfigurable diffractive metalenses (FDMLs) accurately mapped focused wavefront, bandwidth, and focal length. The surface relief metastructures consisted of metal-coated hemispherical cavities in a hexagonal close-packed arrangement to enhance tunable focal length, numerical aperture, and fill factor, FF ≈ 100% through normal and angular light illumination with external stretch. The strain-multiplex of FDMLs approach lays the foundation of a new class of large-scale, cost-effective metalens offering tunable light focusing and imaging.
