*Early childhood development (ESS) is the effective sample size and is used in cases of full matching when matched samples are calculated via stratification and weighting. In the case of this moderation analyses, the ESS for caregivers who received PIM for >12 months is n=534, where there are 289 controls and 245 treated individuals. The ESS for caregivers who received PIM for ≤ 12 months is n=543, where there are 201 controls and 342 treated individuals.
BCa, Bias-corrected and accelerated bootstrap interval; PIM, Primeira Infância Melhor.
