Physical Examination
During the out-patient clinic visit, for both survivors and their siblings we collected data on height, sitting height, weight, waist circumference, hip circumference, blood pressure (three measurements, of which the last two were registered), and pulse. In addition, among survivors we assessed pubertal stage (in survivors <18 years of age), a skin examination was performed, as well as, thyroid palpation, and an assessment of testicular volume among males.
