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

Organic knapping tools made from bone, antler, and wood were essential to early human toolkits but are rarely preserved in the archeological record. The earliest known soft hammers, dating to ~480,000 years ago, come from Boxgrove (UK), where modified antlers and large mammal bones were used alongside flint hard hammers. These tools facilitated complex knapping techniques, such as platform preparation and tranchet flake removal, contributing to the production of finely worked ovate handaxes typical of the Boxgrove Acheulean industry. This study presents a cortical bone fragment from an elephant, deliberately shaped into a percussor for resharpening flint tools. It represents the earliest known use of elephant bone in Europe and the first documented case of its use as a knapping hammer. Reconstructing its life history offers further insights into Middle Pleistocene hominin technological adaptations, resourcefulness, and survival strategies that enabled humans to endure harsh northern environments.
