Retrospective analysis of the case records of 465 babies with a birthweight between 1·0 kg and 2·0 kg, born during 1960-67, showed that 17·9% were described as blue' on arrival in the special care nursery, and that their mortality from hyaline membrane disease was 28·9% as compared with 6·8% in those described as pink'. The overall mortality from hyaline membrane disease was 10·8%. After the adoption of a policy of earlier use of oxygen under intermittent positive pressure, and more careful supervision of the environmental conditions during transfer to the nursery, the proportion of babies described as `blue' on arrival fell to 5·4% (a statistically significant improvement), and the overall mortality from hyaline membrane disease fell to 6·5% (not a significant improvement on the numbers available so far).
对1960年至1967年间出生体重在1.0千克至2.0千克之间的465名婴儿的病例记录进行回顾性分析发现，17.9%的婴儿在进入特别护理病房时被描述为“脸色发紫”，他们因肺透明膜病的死亡率为28.9%，而被描述为“脸色红润”的婴儿这一死亡率为6.8%。肺透明膜病的总体死亡率为10.8%。在采取了更早使用间歇正压给氧政策以及在转送至病房过程中对环境条件进行更仔细监测的措施后，进入时被描述为“脸色发紫”的婴儿比例降至5.4%（有统计学意义的改善），肺透明膜病的总体死亡率降至6.5%（就目前可得数据而言无显著改善）。
