Strengths and limitation
Our study made a detailed investigation of the attitudes and perceptions towards ECS among Chinese reproductive population. To the best of our knowledge, this is the first study to utilize a specific quick response code to conduct the research. It facilitates access to large sample sizes, lower costs, higher efficiency and greenness. The strengths of our study also include that the sample is large and all responses are anonymous. Additionally, the subjects involved in our study are the target population of ECS, including all stages of the reproductive population, such as patients who were pregnant or were trying to conceive with or without assisted reproductive technology.
However, there are still some limitations. Firstly, our participants are people who have not taken an actual uptake of ECS testing and their choices are mostly in hypothetical states. Although the results indicate a high level of willingness to test, not all will actually do so then. Therefore, further studies under actual circumstances of ECS test are needed. Secondly, our participants were mainly from Nanjing and its surrounding areas, which had a relatively high socioeconomic level. Therefore, the population was not representative of the general Chinese population, which may limit the generalization of the results.
