Notes: Model 1 = Time period indicator only, Model II = Model I plus all maternal factors, Model III = Model I plus all socio-economic factors (SES); Model IV = Model I plus all maternal health seeking factors; Model V = Model I plus community level factors and Model VI = Model I plus all other models. T-statistics are shown in the parentheses; *significant at p-value < 0.05. The LRχ2 values refer to those associated with the time period indicator variable.
