CI, confidence interval.

^a Agreement is shown for outcomes classified both in terms of four severity levels of sequelae and in terms of a dichotomous outcome: dependent (i.e. final outcome score: II) or independent (i.e. final outcome score: III–V).

^b Kappa values were interpreted as follows: 0.0–0.2, poor agreement; 0.21–0.40, fair agreement; 0.41–0.60, moderate agreement; 0.61–0.80, good agreement; and 0.81–1.00, very good agreement.³⁰
