Notes: -Each model (except for models 3 and 6) was estimated twice; for the first estimation, economic status and maternal health-seeking behavior were included as continuous variables, all other variables remaining unchanged, and for the second estimation, the quintiles of these variables were included; the table reports coefficients on other variables for the second estimation. A dummy indicator for missing values was also included for each variable with missing values. CI denotes confidence interval.
-Statistical significance: *: P < 0.10; **: p < 0.05; ***: p < 0.001
