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

purposeUnderstanding that a projectile entering the human body can cause damage or destruction to live tissues through a variety of wounding mechanisms - permanent cavity, temporary cavity, and fragmentation - is crucial for researching terminal ballistics and understand the patterns of gunshot wound configuration.

methodsThe present work tested four different types of ammunition in caliber 9 × 19 mm (Full Metal Jacketed, Gold Hex, Copper Bullet Tactical and Bonded), using ballistic gelatin at 10% as soft tissue surrogate. The tests were based on the Federal Bureau of Investigation Protocol and included shots through bare gelatin, heavy clothing, plywood, steel sheets and auto glass. As a comparison parameter, the American-made Federal™ HST, used by several law enforcement agencies in the USA, was also tested in the same conditions.

resultsThe Full Metal Jacketed cartridge had a uniform performance throughout the experiment, showing high penetration levels and no expansion, as expected. Gold Hex demonstrated a strong tendency to fragment with low levels of penetration and weight retention. Copper Bullet Tactical did not achieve the 12" minimum penetration in the soft barrier phases but expanded aggressively. Finally, Bonded only failed to achieve the 12" mark of penetration in phase 5 (auto glass), the hardest barrier in the whole Protocol. Tested for comparison purposes, Federal HST showed aggressive expansion in the initial phases (over 100%), after surpassing the 12" threshold.

conclusionThe study concluded that heavier projectiles (CBC Bonded and Federal HST) performed better than lighter and faster bullets in terms of terminal ballistics.
