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.
