[[Perinatal mortality rates in single and multiple births, and the effects of maternal age, birthweight, and other factors on the perinatal mortality rates in Japan]].
"The perinatal mortality rate (PMR) was analyzed using... Vital Statistics for 1950-1991 in Japan. Secular changes in the PMRs were analyzed according to sex and single-multiple births. This paper also investigated the effects of maternal age, birth order, gestational age, and birthweight on the PMR." (SUMMARY IN ENG)
