Note. CI = confidence interval; GNI = gross national income. Multiple models are adjusted by whether there are national surveys providing representative samples or not: For children younger than 36 months, B = 1.58 (95% CI = −11.41, 14.57). For children aged 36–71 months, B = −5.92 (95% CI = −16.13, 4.28).
