Note. b₀ represents the intercept; b_0–3 represents the coefficient for the first linear segment, b_3–15 represents the following segment and so on until b_60–90. For simplified models, arrows are used to indicate the parameter estimate that applies during the given developmental period. τ represents the random-effect standard deviation in the between study effect size.
