Diagnostic tests, questionnaires, and bio-materials
In Table 2, the numbers of participants who underwent specific
diagnostic tests are displayed.
The following diagnostic tests were performed: 104 24-hour blood
pressures, 311 6-minute walk tests, 1,657 DXA scans, 1,352
echocardiograms, 1,385 electrocardiograms, 1,816 hand grip tests, and
586 pulmonary function tests. The LATER questionnaire was completed by
2,229 survivors (n=473 full / n=1,756 short repeat questionnaire, see
Methods section for explanation). Almost 70% of the participating
survivors also completed the extensive test battery concerning
psychosocial outcomes (data not shown). The following bio-materials were
obtained: 2,257 blood samples, 271 saliva specimens, 657 semen
specimens, 979 urine samples. In total, we extracted DNA for 2,270
survivors, i.e. 90.1% of all participating survivors. Among siblings,
we collected 277 echocardiograms, 272 electrocardiograms, and 278 blood
samples.
