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

The cylinder expansion (CYLEX) test is commonly used to describe the adiabatic expansion of the detonation products and calibrate the equation of state (EOS) of detonation products. A CYLEX test method analogous to the T-20 (pre-set position and record the time of arrival) methodology was developed utilizing a set of probes with radial displacement difference and a high-speed pulse timer to record the radial expansion displacement of the cylinder wall. Two CYLEX tests for Dihydroxylammonium 5,5'-bitetrazole-1,1'-dioxide (TKX-50)-based explosives and two for 2, 4, 6-trinitrotoluene (TNT) were conducted using the CYLEX test method developed, and further Jones-Wilkins-Lee (JWL) EOS parameters of detonation products were determined using the BP neural network and genetic algorithm (BP-GA) program. Besides, the JWL EOS parameters obtained were numerically validated by performing the simulations of the CYLEX test, where the simulation results were consistent with the experimental data.
