Methodology of IHME and WHO.

	IHME	WHO
Modeling process	(1) Data identification (2) Data processing (3) Cause of death ensemble model (CODEm) (4) Proportional model for dividing hierarchical diseases (5) DisMod-MR model for estimation deaths (6) CoDCorrect for scaling cause-specific mortality fraction to sum to 1	(1) Data source identification (2) Data processing (3) Use of one of 3 models to estimate neonatal and postneonatal mortality separately, depending on mortality level, disease profile, and data availability (4) Development of a disease-specific model (5) Adjusting death to sum to the total mortality
Data source	(i) VR (vital registration): over 60% registered data only (ii) VA (verbal autopsy): including all the related paper (iii) Hierarchical disease: systematic review, disease burden estimation paper	(i) VR (vital registration): over 80% registered data only (ii) High mortality & low registered rate: SR with VA (iii) Including regarding intervention effects
Data processing	Considering garbage code of cause of death through all ages	Considering garbage code of cause of death only newborn
