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

The trace elements and rare earth elements in sedimentary rocks are closely related to the sedimentary environment, especially mudstone. Conducting trace element analysis on mudstone is an effective means of studying palaeosedimentary environments. The Cretaceous period in the southwestern part of the Ordos Basin is an important period in geological history; however, research on its geochemical characteristics and palaeoenvironment is still relatively weak. The Huanhe Formation in the Zhenyuan area was selected as the research object. Based on geochemical analysis methods, such as major elements, trace elements, and rare earth elements, the indicative significance of geochemical characteristics for its sedimentary palaeoenvironment was explored. The research results show that CIA and C contents, Ga/Rb, and K
