Reference no 2896 General Notes: Line note 4 Reference no The ThyroMobil study in Mexico covered 23 sentinel sites in 16 districts 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.
