Shown are numbers (n_total) of all analysed infants and number (n_hospitalized) and relative percentage (%) of infants with at least one hospital treatment in the first four year of life (YOL), excluding perinatal hospitalization. For these children the cumulative length of stay and health-care costs are given as median (interquartile range). We used Kruskal-Wallis-test of independence to compare the costs and LOS over the first four years of the exposure groups
