Several estimates because of different outcomes.
Several estimates because of outcomes measured at different ages.
Several estimates because of reporting estimates on different cohorts.
These estimates are not intraclass correlation coefficients obtained using multilevel models but rather correlation coefficients based on two siblings for each family. Thus, these estimates are not strictly comparable to the others.
