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

Existing studies qualitatively rather than quantitatively described the influence of the mechanical property parameters of the impacted body on the overload signal characteristic parameters (acceleration peak AP and pulse width PW) of the projectile. The model of the static mechanical property parameters of the impacted body and the overload signal AP and PW of the projectile were developed in this work. The mechanical properties of the impacted body were changed by heat treatment. The maximum relative errors in the AP and PW of the projectiles predicted by the model versus the experimental results were 1.4% and 3.4%, respectively. The maximum relative errors in the AP and PW of the projectiles predicted by the model and simulated by the finite element software were 14.1% and 24.2%, respectively. The effect of heat treatment of the impacted body on the AP of the projectile was explained. It helps to fill the gap in the field of high-speed impact dynamics in terms of model of the mechanical property parameters of the impacted body and the overload signal characteristic parameter of the projectile, and provides a new method for the selection of the material of the impacted body for impact tests.
