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

As a critical component of the three-phase jet fire monitor head, the nozzle efficiently converts fluid pressure energy into kinetic energy. Optimizing its structural parameters is essential for enhancing jet performance and firefighting efficiency. This study investigates the internal flow field of the nozzle using the VOF method, examining the influence of various structural parameters. The research systematically examines the effects of the nozzle outer wall contraction angle, powder nozzle expansion angle, and length of the nozzle straight section on the internal flow field characteristics. Results indicate that when the nozzle outer wall contraction angle exceeds 25°, the velocity uniformity at the nozzle outlet deteriorates significantly, average turbulent kinetic energy at the outlet of the nozzle increases to 2.37 m
