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

This study investigates the aerodynamic and fuel mixing characteristics of an inclined strut-based injection system for scramjet combustors, focusing on the effects of strut angle and internal air jet assistance. Four configurations were evaluated: annular hydrogen injection with and without internal air four multi-jet, implemented at strut angles of 15° and 7.5°. A series of numerical simulations were conducted to analyze the flow structures, shock interactions, temperature fields, hydrogen mass fraction distribution, and vorticity strength (circulation) downstream of the strut. Results show that increasing the strut angle from 7.5
