Short term and long term maternal mortality according to duration of antenatal HAART (Incidence per 100 PY).

p-values are for the overall sample and refer to person-year incidence.
Strata-specific comparisons were performed: for short term mortality all comparisons were statistically significant except for 91–270 strata against the >270 strata; for long term mortality only the first strata (0–30 days) showed statistically significant differences.
