Endogenous inhibitors of NOS activity. Plasma levels of the endogenous NOS inhibitors asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and N-monomethyl arginine (NMMA) were analyzed in plasma from HC (n = 8), OC ( n = 8), and HN children before [HN (Pre), n =  8] and after [HN (Post), n = 8] surgical management of the obstruction. Data are presented as box-plots, with the median and first and third quartiles (box) and whiskers (minimum to maximum). Asterisk denotes significance at p < 0.05
