a–c, Longitudinal growth mixture models of SDQ total scores in autistic individuals, demonstrating the presence of two groups in the MCS (a), LSAC-B (b) and LSAC-K (c) cohorts. Shaded areas indicate 95% confidence intervals of the line of best fit. d–f, Stacked bar charts show the proportion of individuals who had been diagnosed as autistic at specific ages, categorized by membership in the latent trajectories identified from the growth mixture models in MCS (d), LSAC-B (e), and LSAC-K (f) cohorts. Darker colours indicate male individuals and lighter colours indicate female individuals. P-values are from χ2 tests (two-sided) comparing the distribution of age at autism diagnosis between the two latent trajectories (pooling the two sexes).
