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

This study uses COMSOL and Ventsim software to establish a multibranch horizontal well extraction system model that considers coal body deformation and gas seepage. It investigates the effects of valve opening variations on the negative pressure ratio and system extraction efficiency. The results indicate that when establishing a dynamic control mechanism, the pumping weights of each branch should be considered. When the drilling hole with the highest extraction efficiency is slowly closed, the negative pressure of other drilling holes will significantly decrease in a "double peak" pattern. When the non main extraction source is slowly closed, the increase in negative pressure of the drilling hole is inversely proportional to the extraction capacity; The flow increments of the three sets of dual valve joint control are 1 m
