FIGURE 2.

Cluster analysis identified 2 groups of clinicians according to their tendency to rank patients with higher or lower New York Heart Association/World Health Organization functional class compared with other clinicians. Of the 113 clinicians, 77 (68%) consistently ranked patients in higher functional classes (open circles), and 36 (32%) consistently assigned lower functional classes (closed circles). Independent analyses of the physicians and nurses participating in each of the paper and online groups resulted in an equivalent group pairing (data not shown).
