Prediction of liquid accumulation in a shale gas pipeline.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Liquid accumulation in low-lying and uphill sections of undulating shale gas pipelines significantly threatens transportation efficiency, pressure stability, and pipeline integrity due to corrosion. Accurate prediction of liquid holdup is therefore critical for flow assurance. This study investigates the liquid distribution in a shale gas pipeline through orthogonal testing, analyzing key operational factors including water and gas flow rates. The formation mechanisms and the relative significance of these factors on liquid accumulation are systematically elucidated. Subsequently, a predictive mathematical model correlating operational parameters with liquid accumulation volume is developed. The model's accuracy is rigorously validated against simulation results obtained from the industry-standard OLGA multiphase flow software. The findings of this study establish a theoretical foundation for optimizing pigging operations, thereby enhancing pipeline transport efficiency and reducing operational costs.
