Characteristics of patients in the full-study and propensity score-matched cohorts, stratified by emergency department overcrowding, based on the number of total occupying patients above the third quartile.

Characteristics of patients in the full-study and propensity score-matched cohorts, stratified by emergency department overcrowding, based on the number of total occupying patients above the third quartile.本数据集呈现全研究队列（full-study cohorts）与倾向得分匹配队列（propensity score-matched cohorts）的患者特征，以“在院总患者数（total occupying patients）高于第三四分位数（third quartile）”为判定标准定义急诊科（emergency department）过度拥挤（overcrowding）程度，并据此对患者进行分层。
