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

Sediment biomarkers are important archives of regional, and global climate signatures, particularly in regions which lack continuous terrestrial archives such as the semi-arid deserts of Africa. We measured carbon and hydrogen stable isotopes from plant wax n-alkanes recovered from the Holocene Later Stone Age (LSA) sedimentary sequence at Wonderwerk Cave (South Africa), that comprises several technocomplexes (Kuruman/Oakhurst, Wilton, Ceramic Wilton and Historic). The plant wax n-alkane results were integrated with published palaeoenvironment reconstructions from the cave based on faunal, botanical, geological and sedimentological proxies which provides a robust comparative framework. The findings match well with other proxy records from the same strata and indicate a semi-arid to semi-humid early Holocene, with a mix of woody C
