At least the german Paul-Ehrlich-Institut (which is responsible for the decision here in Germany) states [1]:

> "The number of these cases after vaccination with COVID-19 AstraZeneca is statistically significantly higher than the number of cerebral venous thromboses that normally occur in the unvaccinated population. For this purpose, an observed-versus-expected analysis was performed, comparing the number of cases expected without vaccination in a 14-day time window with the number of cases reported after approximately 1.6 million AstraZeneca vaccinations in Germany. About one case would have been expected, and seven cases had been reported.

1 expected vs 7 observed seems significant. Of course, with tiny rates like that it's challenging to draw a clear conclusion.

Their whole FAQ is very concise and informative: [1] https://www.pei.de/EN/service/faq/coronavirus/faq-coronaviru...

Also, even if we know for sure it's because of the vaccine and of those additional 6 cases, 3 died, we have to keep in mind how many more people would die from covid in 1.6M unvaccinated individuals.
