Baseline characteristics of patients with early, late, and total syphilis and matched control cohorts following propensity score matching. Demographic and clinical variables such as age, sex, race or ethnicity, immunosuppressant use, and history of irradiation were similar across groups.

本数据集收录了经倾向得分匹配（Propensity Score Matching）处理后，早期梅毒、晚期梅毒及全部梅毒患者与匹配对照队列的基线特征。各组间的人口学与临床变量，如年龄、性别、种族/民族、免疫抑制剂使用史及放射照射史，均无显著差异。
