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

Meso-Neoproterozoic to Cambrian oil fields have been discovered in several regions, including Australia and the Middle East. These findings suggest the presence of potential source rocks, despite their long evolutionary history. In the Zhongtiaoshan area of the southeastern Ordos Basin, several outcrop samples were collected from the Xuzhuang, Cuizhuang, and Baicaoping formations spanning the Meso-Neoproterozoic to Cambrian. Geochemical analyses indicate that the Cuizhuang Formation (Mesoproterozoic) exhibits significant hydrocarbon generation potential, characterized by relatively high total organic carbon (TOC) and
