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

Internal floating roof tanks are used to store volatile, flammable, and explosive liquids, making the study of oil vapor diffusion concentration in the gas space of the internal floating roof tank critical for safety management. This study developed a computational fluid dynamics (CFD) model using CFD, based on the Realizable k-ε turbulence model to evaluate the effects of varying liquid levels. (low, medium, high) of the floating roof and external wind speeds on the oil vapor volume fraction. The results indicate that oil vapor volume fraction decreases as the roof rises, indicating that the expansion of the gas space leads to a more dispersed distribution of oil vapor. Additionally, the effect of external wind speed on the evaporation process is minimal and does not significantly influence the diffusion capacity of volatile oil vapor. This study evaluates the safety of vapor concentration relative to the explosion limits of gasoline and n-heptane, providing fundamental guidance for the safe management of storage tanks.
