One thousand, five hundred and nine general practitioners and 795 gynaecologists are co-operating in a large, long-term, controlled, prospective study of the sequelae of induced abortions. The ;case' (6,349 patients) and control (8,132 patients) groups are comparable, and the patients who had induced abortion are also comparable in age, marital status and parity with those in the national abortion statistics. The study should, therefore, give a sound basis for evaluating the long-term hazards of the operation.
1509名全科医生和795名妇科医生正在合作开展一项关于人工流产后遗症的大型、长期、对照、前瞻性研究。“病例”组(6349名患者)和对照组(8132名患者)具有可比性,接受人工流产的患者在年龄、婚姻状况和产次方面也与全国人工流产统计数据中的患者相当。因此,该研究应为评估该手术的长期风险提供可靠依据。
