General Notes:
The ThyroMobil study in Ecuador covered 15 sentinel sites randomly selected in provinces known as iodine deficient in the past; sample selection was done in coordination with the health
authorities, using Ministries of Health's records; SAC randomly selected from one school at each site; goitre investigated by ultrasonography, values not included in the database; same
data reported in reference No. 3615.
UI <50 µg/L: 1.5%, UI <300 µg/L: 45.7%, UI <500 µg/L: 12.8% (data from reference No. 3615).
