Figure 1

Exclusion of maternal islet antibodies. Description of the exclusion of maternal islet antibodies in 545 DIPP or TEDDY participants who had an islet autoantibody-positive sample at or before the age of 0.75 years. Any islet antibodies observed in the child at the age of ≤0.75 years were determined to be of either maternal origin, possibly maternal origin, or nonmaternal origin based on measurement of islet autoantibodies in cord serum sample, the child’s first follow-up serum sample and the maternal serum sample taken during the 1st year after delivery. ^†IAb = islet autoantibody.
