Background
Awareness of COS development and use among Chinese researchers has increased since the concept was introduced in China in 2012. An increasing number of COS have been registered and completed by Chinese developers. The status of relevant COS research led by Chinese researchers and their quality remains unclear.
Methods
An electronic search will be conducted in the COMET, ChiCOS, and Chinese literature databases (CNKI, WanFang, and SinoMed). According to different study types (registration entry, protocol, or completed research), the information of the included studies will be extracted into different Excel tables. The extracted information depends on the type of study. The findings of the review will be presented descriptively. For protocol, we will check the quality with COS-STAP. For completed research, we will check the quality with COS-STAR and COS-STAD. In addition, we will conduct a comparative analysis to determine how many entries in the ChiCOS database have not been registered in the COMET database.
Discussion
This study will provide valuable insights into the current state of COS in China. This is essential for a better understanding of the barriers and facilitators to COS development and application.
