    Collapse Overview 
    Collapse overview
    Dr. Qian is a biostatistician lead for the Division of Epidemiologic Research and the Division of Biostatistics Research. Most of Dr. Qian’s methodological research was inspired by the statistical issues seen in collaborative work, particularly in vaccine safety studies in the areas of the self-controlled study design, sequential analysis, and propensity score analysis. She is also interested in assessing the systematic intervention effects using difference-in-difference design and trends analysis with applications in vaccine, AIDS, and cardiovascular disease research. In addition, her research interests include analysis of longitudinal data, multi-level models, marginal structural models, Bayesian statistics, and survival analysis with competing risks.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
