Table 2 ROC area of identifying sick leaves lasting at least 12 weeks. The ability to identify sick leaves lasting at least 12 weeks in the responder group (n = 152) and in all participants (N = 993), presented as ROC area, calculated from length of sick leave predicted by sick-listed, and mean length predicted by National Insurance medical consultants and officers. The range of the individual National Insurance ROC areas is presented for all participants.

From: Length of sick leave – Why not ask the sick-listed? Sick-listed individuals predict their length of sick leave more accurately than professionals
