Figure 3

Disagreement rates for GCS and FOUR scores. Disagreements of more than one score point in pair-wise ratings of the Glasgow Coma Scale (GCS) score (top panel) and the Full Outline of UnResponsiveness (FOUR) score (bottom panel) respectively. Scores are divided into quartiles. As a substantial proportion of ratings were at the maximum of the each scale (i.e. GCS 15, FOUR 16), the maximum category is shown separately in addition to the quartiles. Disagreements are expressed as a percentage of the total number of ratings in a given quartile of the GCS score and FOUR score, respectively. White bars = disagreements between the neurologists; black bars = disagreements between the neurologists and ICU staff; grey bars = disagreements between ICU staff. For both scores, disagreements were significantly (P < 0.001) less frequent in the maximum category (i.e. GCS 15, FOUR 16) than in all other categories. * For the lowest quartile of the FOUR score, the disagreement between neurologist and ICU staff (P = 0.034) and between ICU staff and ICU staff (P = 0.045) was significantly greater than that between the neurologists.
