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

Background: This study aims to quantify the biomechanical effects of different seat inclinations on the normal and spondylolysis lumbar of pilots under typical fighter aircraft maneuver loads, providing data support for optimizing lumbar protection measures. Methods: Initially, three-dimensional lumbar finite element models of normal, as well as unilateral and bilateral L5 spondylolysis, were constructed, whose effectiveness was verified through mesh convergence and experiments involving vertebral range of motion and lumbar frontal impact. The models were then subjected to rapid pull-up and stable hovering maneuvers to specifically analyze the correlation between seat inclination angles (17° and 22°) and lumbar injuries with different spondylolysis states. Results: The results indicate that the biomechanical responses of three lumbar models under both seat angles remain below injury thresholds. However, the occurrence of spondylolysis at a 22° angle poses a higher risk. Conclusion: These findings are expected to provide a theoretical basis for optimizing seat designs and formulating lumbar protection strategies for pilots with spondylolysis.
