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

Carbon nanotube (CNT) field emission cathodes have attracted considerable attention as electron sources owing to their low turn-on fields and high current extraction capability. Nevertheless, practical application is hampered by intrinsic limitations, including current instability and rapid performance degradation, which stem from the structural state of the CNT film during emission and the strong dependence on the tunneling barrier. Herein, we report a post-annealing deposited CNT (a-d CNT) cold cathode emitter, fabricated via a two-step electrophoretic method, featuring a multilevel NiO
