MMR under four scenarios among 126 LMICs in 2000–2030. Notes: Maternal mortality ratio (MMR) is defined as maternal deaths per 100,000 live births for women of reproductive age (15–49 years). Modest scale-up (Scenario 1): we assumed that coverage of every health intervention increased by 2% per year up to a maximum of 100%. Substantial scale-up (Scenario 2): we assumed that coverage of every health intervention increased by 5% per year to a maximum of 100%. Universal coverage (Scenario 3): we assumed that coverage of every health intervention would reach 95% by 2030
