A high-resolution, multi-method palaeoenvironmental record from pan sediments at Maralaleng Pan, southern Kalahari basin.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 traces in semi-arid environments such as the Kalahari have been linked to the presence of water in the landscape. However, low organic preservation and an uneven distribution of studied sites have resulted in a gap in the knowledge of the environmental conditions under which Homo sapiens adapted to drylands in the Late Pleistocene. The Kalahari boasts numerous seasonal waterbodies (pans) that may provide stratified sequences containing a variety of palaeoenvironmental proxies. Despite this, these environmental archives have rarely been used. In this study, we report on a multi-method investigation of the palaeoenvironmental context of Maralaleng Pan, a pan site with archaeological material in the southern Kalahari basin. Geoarchaeological methodologies, luminescence dating, and plant wax biomarkers have been combined to create a high-resolution palaeoenvironmental record. This contribution reveals that pan sediments from Maralaleng Pan were deposited in an environment characterised by alternating processes indicative of wet (lake) and dry (evaporative) conditions. The integration of our results with the archaeological investigation of Maralaleng Pan suggests that hominins frequented the landscape during a fluctuating lacustrine environment in MIS 5, while the greatest moisture availability occurred during MIS 3.
