My statement is based on Table 1 in the supplementary material which provides IFHS and IBC death rates for a coarse partition: Baghdad, Anbar, High mortality governorates and Low mortality governorates. The corresponding rates for Burnham et al. can be inferred visually from Figure 3 of the paper. Unfortunately, there is no breakdown by individual governorates.
