„World War I – Killed, wounded, and missing“. Encyclopædia Britannica (ინგლისური). ციტირების თარიღი: 2021-03-23. ციტატა: „The casualties suffered by the participants in World War I dwarfed those of previous wars: some 8,500,000 soldiers died as a result of wounds and/or disease. ... It has been estimated that the number of civilian deaths attributable to the war was higher than the military casualties, or around 13,000,000. These civilian deaths were largely caused by starvation, exposure, disease, military encounters, and massacres.“
