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 Cretaceous Formation in Kuqa Depression is the main battlefield for increasing natural gas storage during "the 14th Five-Year Plan" period in Tarim Basin. Engineering problems occur frequently when drilling into very thick gravel layers. In order to clarify the compaction of shallow gravel layer, this paper takes the Bozi-Dabei area as an example, and puts forward the method of "classification of compaction degree based on quadratic clustering". The results show that the method consists of four steps: the selection of characteristic parameters, the clustering effect of single cluster analysis, the classification standard of quadratic cluster construction, and the construction and verification of the classification standard of compaction degree. In the vertical direction, affected by Tianshan uplift and Tuzimazha Salt Wall, the compaction degree of three fan bodies in the study area is significantly different, and the compaction degree of Bozi fan body is stronger than that of Dabei fan body. On the plane, with the increase of source distance, the compaction degree of Bozi 3 fan body decreases due to the influence of gravel composition. The compaction degree of Bozi 1 fan body first increased and then decreased. The compaction degree of Dabei fan body is weak.
