BACKGROUND AND OBJECTIVE: In 1981, @entity137 ( @entity137 ) appeared in Spain, affecting more than 20,000 @entity1 and causing over 2500 @entity204 to date. Previous studies have addressed mortality only by gender and age. We analyzed possible prognostic factors in the survival of the cohort. METHODS: The study period was 1 May 1981 to 31 December 1995 (31 December 1995 was the cut-off date for survivors). The study population consisted of the entire cohort. Overall mortality and @entity137 -related @entity204 were studied. Kaplan-Meier method and Cox regression were used in the analyses. RESULTS: Among the 20,084 subjects in the cohort, 12,164 (60.6%) were @entity1 , and 7917 (39.4%) were @entity1 . Of the 1799 @entity204 , 958 (53.3%) were @entity1 , and 841 (46.71%) were @entity1 ; of the 356 @entity137 -related @entity204 , 234 (65.7%) were @entity1 , and 122 (34.3%) were @entity1 . @entity137 was the leading cause of @entity204 among subjects <40 years of age. Among the @entity137 -related @entity204 , the shortest survival times were for @entity1 and subjects <40 years of age. The major disease manifestations had the highest relative risks (RR) ( @entity409 , RR 3.83; @entity358 , RR 1.54; @entity1897 , RR 2.24; @entity120 , RR 3.19; and @entity1712 , RR 1.14.). CONCLUSIONS: The major clinical manifestations showed worse prognosis for overall and @entity137 -related mortality. Application of these results to the survivors will help clarify the validity of these conclusions.
