We discuss the important role of biostatisticians in clinical research. In addition, the biases that occur in a study, especially "confounding" in an observational study, are discussed using a real example. Finally, the manuscript provides an overview of propensity score matching, a method to eliminate confounding.
我们讨论了生物统计学家在临床研究中的重要作用。此外，还通过一个实际例子讨论了研究中出现的偏差，特别是观察性研究中的“混杂”现象。最后，本文概述了倾向得分匹配法，这是一种消除混杂的方法。
