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

Space division multiplexing (SDM), particularly multi-core fiber (MCF) technology, represents a promising solution for high-density cabling in duct-constrained scenarios such as submarine cable systems. Although recent laboratory experiments and prototype trials have demonstrated the feasibility of MCF-based submarine cables, a complete optical communication validation of a real-world MCF submarine cable link incorporating optical amplifiers has remained a critical necessity. Here, we demonstrate a field validation of the MCF submarine cable communication with an end-to-end system. Based on a field-deployed 7-core fiber submarine cable infrastructure, we achieved a record-breaking net transmission rate of 410.5 Tbit·s
