Mental component summary^bc	49.3	(9.4)	50.6	(9.6)	-1.3	(-4.7 to 2.1)	0.463

Domain scores are given in percentage (range 0-100) and higher scores indicate better health-related quality of life
Component summaries are given as T-scores based on an average of 50 points and a standard deviation of 10 points
CI, confidence interval; SD, standard deviation; SGA, small for gestational age
^aMean difference adjusted for sex, confidence interval and p-value based on bias-corrected and accelerated bootstrap (BCa)
^bData missing for one SGA participant
^cData missing for one control participant
