Cholesky Decomposition of Additive Genetic (A), Shared Environmental (C), and Non-Shared Environmental (E) Influences (95% Confidence Intervals) for Hyperactivity/Impulsivity across time

Note. Estimates whose lower limit of 95% confidence interval (two-tailed) is larger than 0.01 are bolded. Across each row, total A, C, and E equal to the sum of estimated A, C, and E across all time, respectively, representing the relative contributions of genetic and environmental influences cumulated from previous times. For instance, for total A in time 3 (0.43), it equals to the sum of A of all three time points (0.40 = 0.12 + 0.31 + 0.00). In the last column for total A, C, and E, their estimates sum to 1 for each time. For instance, for time 2, A (0.01) + C (0.47) + E (0.53) = 1.
