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
Ultraflat, single-crystal Cu(111) thin films are widely regarded as ideal epitaxial substrates for synthesizing two-dimensional single crystals for ease of subsequent transfer and device integration. However, the fabrication of Cu(111) remains hindered by a lack of scalable and reliable technique to eliminate in-plane twin boundaries (TBs) in final films. Here, we present a method to address TB issues for harvesting ultraflat, TB-free Cu(111) wafers, which also enable the growth of high-quality, single-crystal graphene wafers. It has been revealed that the deposition of Cu films with designed texture would enable the selective abnormal grain growth of specific Cu(111) during high-temperature annealing, allowing for the production of 6-inch TB-free Cu(111) wafers with high crystallinity (misorientation angle of 0.48°), flatness (
