Sensitivity analysis of the model to predict low birthweight: Comparison of the regression coefficients, standard errors (SE), and p-values for complete case analysis (CCA) and multiple imputation (MI) for generalized linear mixed model fit by maximum likelihood. (Number of cluster = 10, Standard deviation = 0.06308).

* Variables retained in the reduced model using likelihood ratio test are: age, BMI, hemoglobin, education, gravidity, comorbidity, unplanned pregnancy, and alcohol use. § Comorbidity include pulmonary: history of asthma or COPD (chronic obstructive pulmonary disease); cardiac: history of heart failure or ischemic heart disease; renal diseases. BMI: Body Mass Index; ANC: Antenatal care.
