Number of poor responders for SGA patients (bold) and GHD patients (italic). SGA = small for gestational age; GHD = growth hormone deficiency; SDS = standard deviation score; ∆Ht = first-year gain in height; HV = height velocity; SR = studentized residual. * HV < − 1 SD for expected first-year treatment response based on reference data developed by Ranke et al.
