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

Human dispersal across the Bering Land Bridge (BLB) was a key event in the peopling of the Americas, but Beringia's archaeological record remains poorly understood. In response, the Shég' Xdaltth'í' site in interior Alaska has been the focus of a multi-disciplinary study since 2016. The site contains three archaeological components dating to the Late Pleistocene, 13.8, 13, and 12.7 thousand years ago. The oldest component yielded an expressive array of cultural remains, including a unique hafted-biface form, osseous tools, diverse fauna, and well-preserved activity areas, a record unparalleled for this age in Beringia. Shég' Xdaltth'í' represents the earliest known Nenana Complex occupation east of the BLB, and its distinct hafted-biface form occurs in coeval sites west of the BLB, providing an important trans-Beringian cultural link. Although not Beringia's oldest site, Shég' Xdaltth'í' reveals important information about Late Glacial peopling and settling-in behavior in this far northern setting.
