(a) Different numbers of pairs for each symptom as not all symptoms assessments were completed by both patient and carer in each pair. (b) Two-way mixed effect model; absolute agreement definition; single measure ICC. (c) <0.20 as poor agreement; 0.20–0.39 as fair agreement; 0.40–0.59 as moderate agreement; 0.60–0.79 as substantial agreement; and 0.80–1.0 as excellent agreement
