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

Ångström-scale polygonal rings in monolayer amorphous carbon (MAC) enhance its electronic and mechanical properties while providing unique ångström pores for precise subatomic species separation, essential for advancements in catalysis, energy and medicine. However, the absence of an industrial-scale synthesis method for intrinsic MAC has limited its technological applications compared with graphene and bulk amorphous materials. Herein, we report an industry-compatible disorder-to-disorder synthesis approach to achieve wafer-scale ultraclean MAC (UC-MAC) within a timescale of seconds, featuring optimized ångström polygons without detectable metal contamination, and nanosized pores. In contrast to metal-contaminated MAC, UC-MAC allows atomic-scale characterization of intrinsic electronic properties and functions as an ångström-scale membrane, facilitating the splitting of high-flux H
