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

Passive optical networks (PONs) serve as the backbone of modern all-optical communication infrastructures, while fiber-optic distributed acoustic sensing (DAS) is being applied to various fields as a revolutionary technology. Here we present a study on seamless integration of PONs and DAS for human intrusion monitoring by designing an intensity time-varying frequency shift keying with subcarrier composite spectrum modulation (ITVFS-SCSM) scheme, allowing us to overcome the limitations imposed by the high transmission loss of optical splitters and the low extinction ratio of electro-optic modulators in PONs to the performances of DAS. The ITVFS-SCSM scheme designed can simultaneously realize communication and sensing functions with excellent component and modulation compatibilities within a single channel. Assisted by a time difference of arrival algorithm, the localization of human intrusion with sub-meter accuracy with a high DAS sensitivity of 36.5 pε Hz
