Strengths and difficulties assessment (SDQ)
n=2/8
SDQ results were available for seven participants (39%; IVIG n=5/10 (50%), placebo n=2/8 (25%)) at 4–8 weeks after discharge from acute care and eight participants (44%; IVIG n=6/10 (60%), placebo n=2/8 (25%)) at 12 months after randomisation.At 4–8 week after discharge from acute care, five participants (28%; IVIG n=4 (40%); placebo n=1 (13%)) had a close to average SDQ score, one participant (6%; IVIG n=1/10 (10%)) had a slightly raised SDQ score and one participant (6%; placebo n=1/8 (13%)) had a very high SDQ score. At 12 months after randomisation, the same number of participants had a close to average score and slightly raised score, but two participants (11%; IVIG n=1/10 (10%), placebo n=1/8 (13%)) had a very high SDQ score.
