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

The Guliya (Tibet) ice core drilled in 1992 (GP1992) has garnered special interest because of its exceptionally long timescale of ~760 thousand years. This timescale makes GP1992 currently the second oldest ice core in the world, much older than any other extrapolar ice cores. Here, we revisit the GP1992 timescale by dating a Guliya ice core (GP2021) that was drilled close to the GP1992 drilling site in 2021. All our data, including the absolute dates deduced from
