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

Accurate long-distance ranging is crucial for diverse applications, including satellite formation flying, very-long-baseline interferometry, gravitational-wave observations, geographical research, etc. The integration of the time-of-flight measurement with phase interference in the dual-comb method enables high-precision ranging with a rapid update rate and an extended ambiguity range. Pioneering experiments have achieved remarkable absolute ranging precision over short paths. However, achieving similar precision over longer distances remains technically challenging due to high transmission loss and noise. In this article, we propose a bistatic dual-comb ranging approach that enables successful ranging over a distance of 113 km. We employ air dispersion analysis and a synthetic repetition rate technique to extend the ambiguity range of the inherently noisy channel beyond 100 km. The achieved ranging precision is 11.5 [Formula: see text]m @ 1.3 ms, 681 nm @ 1 s and 82 nm @ 21 s, as confirmed through a comparative analysis of two independent systems. The advanced long-distance ranging technology is expected to have immediate implications for space research initiatives, such as the space telescope array and satellite gravimetry.
