  2. Notes: The table shows the effect of UEBMI coverage on six birth outcomes. Each panel presents the results of the propensity score matching approach on a separate birth outcome. Birthweight Panel determined the infant birth weight (in grams); Premature Panel for gestational weeks < 37; Low Birth Weight Panel for birth weight < 2500 g; Very Low Birth Weight Panel for birth weight < 1500 g; Low Apgar Score Panel Apgar score determined Apgar score <  7; Abnormal health condition at birth Panel based on the International Classification of Diseases, 10th Revision, Clinical Modification (1CD-10-CM), equres one means if the baby had any disease diagnosis
