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

Over the past decade, the reported planar vacuum electron tubes (VETs) have not yet succeeded in resolving the gate leakage issue due to inherent limitations of their working principles, preventing their circuit integration thus far. This paper proposes a cathode modulated vacuum/air channel electron tube (CMVET), which completely solves the long-standing gate leakage problem. Furthermore, the developed CMVET has been integrated into fundamental circuit blocks and successfully applied in common-source amplifiers, differential amplifiers, cascode amplifiers, as well as NOR and NAND gates, thereby demonstrating its functionality and laying a foundation for further research on monolithic electron tube integrated circuits.
