*The number of participants refers to the number that was present in the aNGT sessions and provided weights.
†Weighing was planned to be repeated in both online sessions, but not done in online session two due to time constraints. The first percentage of online 1 is the result after the first weighing, the second shows the result after the weighing step was repeated.
