Annual odds ratios, standardised for known confounding variables, were used to examine trends in outcome at 3 years of age among 1499 infants of less than 1500 g birth weight admitted to a regional referral centre between 1980 and 1989. Despite improved survival, the chance of survival with a major disability or with cerebral palsy was unchanged. The likelihood of dying or surviving with a major disability significantly reduced during the decade.
对已知混杂变量进行标准化后的年度比值比,用于研究1980年至1989年间入住某地区转诊中心的1499名出生体重低于1500克的婴儿在3岁时的预后趋势。尽管存活率有所提高,但伴有严重残疾或脑瘫的存活几率并未改变。在这十年间,死亡或伴有严重残疾存活的可能性显著降低。
