The risk of stillbirth was compared between groups by time to event analyses using gestation as the time scale and antepartum stillbirth as the event.
The proportions of LBW infants, SGA infants, preterm deliveries, stillbirths, and mean birth weights were compared across the five fuel categories (gas, kerosene, charcoal, wood, and cow dung).
Reproductive outcomes: Miscarriage, abortion, live birth, ectopic pregnancy, stillbirth in the exposed group were compared with the unexposed cohorts.
Our pooled analysis however failed to show a statistically significant reduction in stillbirth when antiretrovirals for pregnant women were compared to placebo (RR = 0.93; 95% CI 0.45 – 1.92) and thus no recommendations have been made for LiST regarding this intervention.
They were compared with 310 women with single ongoing pregnancies and gestation matched to that at which the stillbirth occurred.
Secondly, the intangible costs, in addition to direct/indirect costs of stillbirth could be compared more realistically to the costs of other maternal or fetal outcomes such as live-births and premature births.
Specific aetiologies of the 217 examined stillbirths were also compared with the previous study at the same institution.
The number of stillbirths was again compared with the expected number based on ONS published data.
Multifetal pregnancies and stillbirths were excluded, as they carry a different set of risks compared to singleton live births.
The vast majority of the stillbirths occurred in term pregnancies, but, compared to intrapartum stillbirths, a larger proportion of antepartum stillbirths were in preterm pregnancies (Table 4).
