Table 2 Wilson efficient-score method, corrected for continuity to measure the proportion of agreement between the two observers

Proportions of agreement				95% CI
Decision	Maximum possible	Chanceexpected	Observed	Lower limit	Upper limit
Normal	0.8485	0.2169	0.5250	0.3634	0.6818
Steatosis	0.5789	0.1961	0.3953	0.2537	0.5555
Hepatitis	0.5517	0.1381	0.5000	0.3168	0.6832
Cirrhosis	0.3333	0.0089	0.3333	0.0177	0.8747
Composite	0.7882	0.3084	0.6353	0.5232	0.7350

The greatest agreement concerned normal patients (84.85%), while the smallest concerned cirrhosis patients (33.33%).
