Numbers of observed cases in each of three levels of oestrogen receptor (ER) positivity on tumours processed in each of seven hospitals. Expected values are calculated based on the proportions of cases in all cases submitted (ER negative, 19; ER moderate, 104; ER strong, 297). The κ2 values for each cell are shown, allowing identification of those results contributing most to the overall κ2 value. | ||||
