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

Fractional Chern insulators (FCIs) generalize the fractional quantum Hall effects of Landau levels to lattice systems in the absence of an external magnetic field, which arise from the interplay between strong electron-electron interactions and non-trivial topology. Despite extensive theoretical proposals over more than a decade, realizing intrinsic FCIs in realistic materials has remained a long-standing challenge, owing to stringent requirements on band flatness, topology and quantum geometry. Advances in two-dimensional moiré superlattices have overcome these obstacles, enabling observations of the fractional quantum anomalous Hall effect. In this Perspective, we review the theoretical foundations of FCIs and discuss their experimental realizations in moiré materials, with a focus on two complementary platforms: twisted MoTe
