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.
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
This study examines the influence of geopolitical risk (GPR) on the stock returns of 75 global representative defense companies. Our argument is based on the premise that the Crimean Peninsula's 2014 annexation was a turning point for the defense industry. The study uses wavelet coherence and phase differences to examine daily datasets spanning from January 1, 2014 to December 31, 2023. We find that 50.6 % of the defense companies experienced immediate effects following the Crimean Peninsula's annexation. Among all headquarters, the reaction of companies from Europe, the US, and South Korea in 2014 was noteworthy. Subsequently, during the COVID-19 pandemic, 30.6 % of companies recorded movements with a medium frequency, revealing negative and moderate influence. Furthermore, the Russia-Ukraine war impacted the stocks of 81.4 % of the defense companies in our sample. The results clearly demonstrate the defense industry's global growth trend, particularly after 2014. Additionally, the conflict between Israel and Hamas that began in October 2023 has had a local effect on the Israeli defense industry without contributing to the spread of GPR. The study concludes that investors and decision makers must shift orientation toward knowledge of defense industry stocks to hedge and diversify the risks induced by GPR.
