From: Capturing patient experience: does quality-of-life appraisal entail a new class of measurement?
Standards of Comparison: Z-to-r Distance between patient-group pairs for item-to-item correlations. This graph displays results from the first ANOVA. Each of 15 patient-group pairings is characterized on the Y-axis by the mean distance among 28 pairs of item-to-item correlations. Patient-group pairings showing similar item-to-item correlations (low mean distances) appear at right. Mean distances are widely dispersed, ranging from 0.04 to 0.35. 95% confidence-interval error bars are shown above and below the point estimate
