Analyses assessed agreement between wear logs (adult or parent) and sensor data scored using the TT method and the human raters (four raters). Kappa statistics could not be determined for participant 3, as the parent reported no spectacle wear, or for participant 9/rater 1, as the child had no spectacle wear per rater 1 assessment.

^aUsing group optimized threshold of ≥28.00°C.

^bPer the parent of participant 3, the child had no periods of wear.

^cIncludes all child data and controls for within-subject dependence.
