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

purposeTo investigate injury mechanisms and vulnerable regions for severe pulmonary contusion (PC) in astronauts during off-nominal capsule landings, establishing critical injury thresholds.

methodsSix distinct high-intensity landing scenarios (≤52.1 g) were simulated using a drop-tower test stand and a Hybrid III anthropometric test device(ATD). The Total Human Model for Safety (THUMS) finite element model (FEM) was utilized to simulate thorax-pulmonary dynamics at a 40° supine posture. Injury risk was assessed using the Viscous Criterion (VC), strain/strain-rate thresholds, and Abbreviated Injury Scale (AIS) criteria.

resultsAt 37.1 g impact (VC

conclusionThis study defines 37.1 g as the critical threshold for AIS 4 + thoraco-pulmonary trauma, elucidating the S5 compression mechanism and its association with high-risk RFs (1st, 9th, 10th). These findings provide a biomechanical foundation for enhancing astronaut survival protocols, enabling rapid post-impact triage, targeted pulmonary intervention (focus right S5 segment), and the design of energy-absorbing countermeasures to mitigate visceral compression.
