How many babies were born in the country during the war compared with the three years before it, and how births moved in the same years in countries without war. It is a comparison, not proof that the war alone did it.
Two lines: births in the country and the median of the comparison countries; 100 is the average of the three pre-war years. The red band marks the war years; the dot, the year with the fewest births.
