We have reanalysed the clinical and laboratory data on 196 individuals with Graves' disease. The consensus of two clustering techniques and a new method of allocating patients to a cluster resulted in two groups of patients, those with a severe and others with a mild disease. The severe disorder is characterized by a high frequency of HLA‐B8 and‐Al, a low complement level, high titres of circulating immune complex and anti‐thyroglobulin antibody, a high lymphocyte transformation index and serum T3 level, a low level of active E‐rosettes, large goitres and a high value for the Crooks test. The mild disorder shows a higher frequency of HLA‐B12 and an abnormally low absolute lymphocyte number. A weight was calculated for each character according to the relative frequency in the two clusters. A total score could then be calculated for each patient based on their clinical and laboratory findings. There were two distinct distributions of scores corresponding to the two subgroups. This suggests different aetiological factors which may be more easily studied in these more homogeneous groups. Prognostic predictions can be made using the score. The risk of recurrence and the frequency and severity of ophthalmopathy increases dramatically as the score increases. The use of the score in making therapeutic decisions needs to be tested.
