(a) Trajectories of development of alcoholism symptomatology over age 15
to 45, for men. The smooth lines marked by triangles are the predicted
trajectories from the model, and the lines marked by circles are the actual
number of symptoms at each time point for the group. (b) Trajectories of
development of alcoholism symptomatology over age 15 to 45, for women. The
smooth lines marked by triangles are the predicted trajectories from the model,
and the lines marked by circles are the actual number of symptoms at each time
point for the group. YAO, Young adult onset; CUML, developmentally cumulative;
DL, developmentally limited.
