Baseline = first questionnaire filled in 0 to 2 days before discharge from hospital; follow-up = about 7 years after baseline; recall = recollection of baseline QoL about 7 years later; CI = confidence interval.
*p < .05;
**p < .01;
***p < .001.
Significant t-scores after Bonferroni correction (pƗ = p * 10) are presented in boldface.
