Looking at the wikipedia it seems they didn’t suffer many military casualties but suffered a lot from civilian deaths by military action at 1.5 million, probably mostly the Armenian genocide which estimates put at about 1 million. Also another 1 million from increase in civilian deaths which is harder to determine, maybe the empire was reliant on food imports pre-war that went away once the allies took control of the Mediterranean and blockaded them.
