From 1973 to 1974, 3061 cases of pregnancy were assessed according to a modified risk score system for the early recognition of pre- and dysmaturity at the Universitätsfrauneklinik of Jena (Clinic of Gynecology and Obstetrics). As a result of our investigations, we can state the certain correlations between premature birth and risk factors can be recognized. In the particular case an unequivocal establishment of the prematurity risk is not possible.
1973年至1974年期间，耶拿大学妇产科医院根据改良风险评分系统对3061例妊娠病例进行了评估，以便早期识别早产和未成熟情况。根据我们的调查结果，可以确定早产与风险因素之间存在一定的相关性。但在个别情况下，无法明确确定早产风险。
