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
From atomic crystals to macroscopic material structures, twisted bilayer systems have emerged as a promising route to control wave phenomena. In few-layer van der Waals materials, however, the intrinsically weak interlayer coupling typically demands precise control of small twist angles to reach magic-angle conditions. Here, we show that twisted one-dimensional photonic crystal bilayers can overcome this limitation by accessing a regime of strong interlayer coupling-comparable to intralayer coupling. This strong coupling enables ultrawide flat-band formation even at large twist angles. We experimentally realize this regime by stacking tungsten disulfide gratings using a two-step lithography method, resulting in ultrawide chiral flat-band cascades in magic-angle twisted bilayer gratings. Our work not only provides a platform for designing photonic applications with a tunable photonic band but also explores a previously unidentified regime of physics that is unattainable in conventional solid-state-based moiré systems.
