This summarises the results of a direct comparison of howRu and EQ-5D in 116 patients at a cardiovascular out-patient clinic. howRu is shorter than EQ-5D, with better readability statistics, a higher completion rate, a wider range of states used and a smaller ceiling effect. The correlation between howRu and EQ-5D (r=0.70) is like those of other validated instruments with EQ-5D.
