*Models clustered around country.
†Moderate complications (heavy bleeding, suspected intra-abdominal injury or infection).
‡Mild complications (based on abnormal physical examination findings on initial assessment (vital signs, appearance, mental status, abdominal examination, gynaecological examination)).
§PLTC, potentially-life threatening complications (WHO potentially-life threatening conditions (severe haemorrhage, severe systemic infection or suspected uterine perforation)).
¶SMOs, severe maternal outcomes (WHO near-miss criteria and mortality).
