  1. Overall mean percentage meeting the measure for each measure, and the centre specific 10th, 50th and 90th percentiles. Only centres with five or more patients were taken into account. Statistical significance between median centre specific score for the threshold measure and the clinical action measure was tested by the Wilcoxon-test: p < 0.001 (°) and p < 0.01 ($) vs. the threshold measure
