index event的翻译

The date of the first-time diagnosis of aortic dissection was defined as the index event.
Since the aim of our study was to include only new cases, we excluded patients diagnosed during 2000–2001, thereby securing that patients included in 2002–2016 had not been diagnosed with dissection prior to the index event.
这里的index event是指特定事件吗
求高人赐教，拜托🙏🏻
