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 registryThe 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.

6 · The paper itselfAbstract
Berry curvature dipole (BCD) describes the dipole-like distribution of Berry curvature in momentum space and plays a key role for quantum geometric phenomena in nonlinear optoelectronics. Experimentally, BCD can be generated at artificially designed semiconductor heterointerfaces where rotational symmetry breaking is induced by interfacial lattice mismatch. Such a local interface symmetry breaking strategy is largely limited to the monolayer regime; however, how to induce BCD in thicker semiconductors remains challenging. Here, we demonstrate a strategy for BCD generation in semiconductors beyond the monolayer limit via ferroelectric-polarization-driven symmetry breaking in WSe
