Limitations
Several limitations of this study should be noted. First, it is very difficult to conduct a rigorous randomized observational survey. There is unavoidable selection bias in this study. Second, the survey may have been subject to bias ascertainment as only university affiliated hospitals and university teaching hospitals were selected, making it likely that the degree of neuroprognostication awareness and practice reflected in our survey is an optimistic perspective. The true proportion may be lower than that reported in this study.
