Outcomes and exposures in children with complete data (N = 4,706).

* Frequency distribution weighted by each child’s posterior probability of class membership.** “Age 3 years or later, not before” = owned at or after age 33 months but not at any time before; “Before and after age 3 years” = owned at any time before age 33 months and at any time thereafter; “Before but not after 3 years” = owned at any time before, but not owned at or at any time after, age 33 months.Outcomes and exposures in children with complete data (N = 4,706).基于每名儿童的类别归属后验概率（posterior probability）加权的频数分布。其中：「3岁及以上（而非此前）」指在33月龄及之后拥有该物品，但此前任意时间均未拥有；「3岁前后均拥有」指在33月龄前的任意时间及之后的任意时间均拥有该物品；「3岁前拥有但3岁后未拥有」指在33月龄前的任意时间拥有该物品，但在33月龄及之后的任意时间均未拥有。本分析聚焦具备完整数据的儿童的结局与暴露因素（N=4706）。
