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

Multiple toxic gases, such as carbon monoxide (CO), are generated after blasting of plateau tunnel. To investigate the migration patterns of CO during the ventilation process following blasting in high-altitude tunnels, this paper employs a three-dimensional model of tunnel blasting excavation under push ventilation. The study utilizes computational fluid dynamics to explore the temporal and spatial evolution characteristics of CO under various operational conditions. The influence of relevant factors was quantified using the grey relational analysis method. Numerical simulations were then used to derive distribution functions for CO concentration in relation to altitude, ventilation time, and other factors. The results indicate that under the influence of push ventilation, multiple vortex regions form due to the interaction between ventilation jets and several recirculation areas, where the airflow velocity is slower and CO concentrations are higher compared to other nearby regions. The grey relational analysis method yielded correlation factors of 0.634039, 0.6572, and 0.6560 for altitude (H), distance from duct outlet to working face (L
