Estimated Marginal Slopes

LL-Neg (a) HL-Neg (b) HL-ASD (c)
EMS (SE) EMS (SE) EMS (SE) Pairwise Comparison
Early Gesture
 Interaction 2.75 (.13) 2.80 (.10) 1.93 (.18) c < b, a
Later Gesture
 Interaction 11.10 (.35) 10.94 (.26) 7.51 (.47) c < b, a

Notes. HL-ASD, high likelihood for autism infants who were diagnosed with ASD at 24 months of age; HL-Neg, high likelihood for autism infants who were not diagnosed with ASD at 24 months of age; LL-Neg, low likelihood for autism infants who were not diagnosed with ASD at 24 months of age. Pairwise comparison indication is based on Tukey adjusted p-value of p < .05; EMS indicates estimated marginal slopes; SE indicates standard error.
