Table 4 The moderating effects of age group and childcare environment on the differences for change in-care physical activity and sedentary time (follow-up vs. baseline) between groups (accreditation vs. control)

From: The impact of new government childcare accreditation standards on children’s in-care physical activity and sedentary time
