Thorac. cardiovasc. Surgeon 40 (1992) 59-64

In the above article reference is made to Fig. 3a, b ‘Mean HRPD scores’ and to ‘The mean values of the four measurements within the three subgroups’. In fact eight assessments (‘measurements’) at four points in time were made for each patient, so that Fig. 3a, b should have displayed eight diagrams and not just four. Unfortunately, this ommission was not noticed until it was too late. The missing scores are given in tabular form below:
