  1. t-scores for comparison of medial-lateral postural sway of infants with typical development and with delayed development, based on approximate entropy calculated with various lag and r values, -3.32 is the largest magnitude t-score.
  2. Note: t-scores with magnitude equal or larger than 3.04 are indicated with * and are in bold.
