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

Understanding the formation and interactions of out-of-phase cavitation bubbles is crucial for comprehensively exploring cavitation processes in both nature and engineering applications. In this study, a numerical model for the interaction of out-of-phase cavitation bubbles is developed using the hybrid thermal lattice Boltzmann method, where cavitation bubbles are solely excited by thermal nucleation. Furthermore, a new temperature distribution function for thermal nucleation is proposed, enabling a more stable generation of cavitation bubbles. By comparing the results with those obtained from the Rayleigh-Plesset equation incorporating the thermal effect term, the validity of the thermal nucleation model has been verified. Subsequently, the validity of two out-of-phase cavitation bubbles model is experimentally verified, and the dynamic and thermodynamic behaviors of two out-of-phase cavitation bubbles are systematically investigated. The behaviors are primarily influenced by the dimensionless bubble spacing l
